[0076] like Figures 1 to 11 As shown, according to an embodiment of the present invention, a cooking utensil 100 is proposed, which includes a cavity assembly 13, an air intake assembly 30, a hot air assembly 50 and an exhaust assembly 40. The cavity assembly 13 surrounds a cooking cavity 131. The air intake assembly 30 is arranged at the outside of the cooking cavity 131 and is connected to the cavity assembly 13. The air intake assembly 30 is used to send external air into the cooking cavity 131. The hot air assembly 50 is arranged at the outside of the cooking cavity 131 and is connected to the cavity assembly 13. The hot air assembly 50 is communicated 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 arranged at the outside of the cooking cavity 131 and is connected to the cavity assembly 13. The exhaust assembly 40 is used to discharge the air in the cooking cavity 131 to the outside.

[0077] Specifically, the cavity assembly 13 includes multiple plates, which are spliced ​​together to form a cooking cavity 131. When food needs to be cooked, the food is placed in the cooking cavity 131 and cooked by heating to meet the user's usage needs.

[0078] One end of the air intake component 30 is connected to the outside, and the other end is connected to the cooking cavity 131. Driven by the air intake component 30, the outside air can enter the cooking cavity 131. After the outside air enters the cooking cavity 131 driven by the air intake component 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 component 40 can be increased, so that the discharge speed of the air flow through the exhaust component 40 is increased.

[0079] The heating chamber of the hot air assembly 50 is connected to the cooking chamber 131. When the hot air assembly 50 is in operation, the air flow can circulate between the cooking chamber 131 and the heating chamber of the hot air assembly 50. When the hot air assembly 50 is in operation, the air flow can only circulate between the heating chamber and the cooking chamber 131 without heating the air flow, or the air in the cooking chamber 131 can enter the heating chamber to heat the air flow, and then send the heated air flow into the cooking chamber 131.

[0080] According to the cooking appliance 100 of the present invention, when food is cooked and the steam needs to be discharged, the air intake component 30 and the hot air component 50 are controlled to operate, and the air intake component 30 sends outside air into the cooking cavity 131. After the outside air enters the cooking cavity 131, it can dilute the steam, and also increase the pressure of the gas in the cooking cavity 131, so that the speed of steam discharge in the cooking cavity 131 is increased. The hot air component 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 impact of steam on the food cooking process, thereby improving the cooking quality of food, and enhancing the user experience.

[0081] In some embodiments of the present invention, the air intake assembly 30 includes an air intake fan 31 and an air duct 32, the air intake port of the air intake fan 31 is connected to the outside, one end of the air duct 32 is connected to the exhaust port of the air intake fan 31, and the other end of the air duct 32 is connected to the cooking cavity 131.

[0082] Specifically, Figure 1 As shown, the cooking appliance 100 includes a body 10, which includes a cavity assembly 13, a door assembly 11 and a base assembly 12, wherein 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.

[0083] The cavity assembly 13 includes a plurality of plates and an outer cover 135. The plurality of plates are enclosed to form a cooking cavity 131. The outer cover 135 is disposed on the outside of the plurality of plates. There is a space between the outer cover 135 and the outside of the plurality of plates. The air intake fan and the air guide 32 are disposed in the space. The air intake 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. The outer cover 135 is provided with air holes (such as grille holes or mesh structures, etc.), the air inlet of the air intake fan 31 is disposed opposite to the air holes, and the outlet of the air intake fan 31 is connected to the cooking cavity 131 through the air guide 32.

[0084] The connection method of the air duct 32 and the exhaust port of the fan includes but is not limited to plugging or connecting via a connector. The cavity assembly 13 is provided with a connecting structure that is connected to the cooking cavity 131. The connection method of the air duct 32 and the connecting structure includes but is not limited to plugging or connecting via a connector. By providing the air duct 32, the air intake fan 31 can be effectively connected to the cooking cavity 131, so that the air intake fan 31 can be reasonably arranged and installed, thereby improving the overall compactness of the structure.

[0085] The air duct 32 is a flexible tube (such as a rubber or silicone tube, etc.), which is easy to set up and install, and can effectively improve the convenience of assembly, thereby effectively improving the rhythm of production and improving the efficiency of production. Setting the air duct 32 as a flexible tube can make the air duct 32 smoothly transition at the turning position, thereby reducing the obstruction to the airflow, and further reducing the impact on the flow rate of the airflow.

[0086] It should be pointed out that in the present application, the air intake fan 31 is a centrifugal fan, which has a high rotation speed and a better driving effect on the airflow, and can effectively increase the amount of airflow delivered into the cooking cavity 131.

[0087] In addition, the air intake fan 31 includes a fan body 311, a first bracket 312 and a second bracket 313. The first bracket 312 is connected to the top of the second bracket 313 (the connection method includes but is not limited to snap-on, bonding, welding or connection via a connector, etc.) and encloses an installation space. The fan body 311 is arranged in the 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. Such an arrangement can, on the one hand, improve the fixing strength of the fan body 311, 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 reduce the vibration and noise of the whole machine during operation.

[0088] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the air intake assembly 30 further includes a one-way valve 33 , which is disposed in the air duct 32 , and is configured to conduct air in a one-way manner from the air intake fan 31 to the cooking cavity 131 .

[0089] Specifically, the air intake fan 31 is connected to the cooking cavity 131 through the air duct 32 . Driven by the air intake fan 31 , external air enters the cooking cavity 131 through the air duct 32 to assist in the discharge of steam in the cooking cavity 131 .

[0090] A one-way valve 33 is provided in the air duct 32, and the air duct 32 is set to a one-way conductive structure by means of the one-way valve 33, so that the airflow can only be unidirectionally conducted from the air intake fan 31 to the cooking cavity 131, thereby reducing the backflow of the airflow in the cooking cavity 131 through the air duct 32 (i.e., the airflow in the cooking cavity 131 enters the fan through the air duct 32), thereby reducing the adverse effects of the backflow of the airflow on the air intake fan 31 and other components.

[0091] It should be understood that, in the present application, the one-way valve 33 refers to a general term for a component that can achieve a one-way conduction function, that is, any component that can achieve a one-way conduction function can be understood as the one-way valve 33 in the present application.

[0092] It should be pointed out that the one-way valve 33 is arranged in the air duct 32, wherein the setting position of the one-way valve 33 can be the connection end between the air duct 32 and the intake fan 31, or the connection end between the air duct 32 and the cavity assembly 13, or the area between the two ends of the air duct 32.

[0093] In some embodiments of the present invention, Fig. 9 As 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. A gas channel is provided on the valve seat. The valve core 333 is movably arranged on the valve seat. Along the direction from the air intake fan 31 to the cooking chamber 131, the valve core 333 can move relative to the valve seat and open the gas channel.

[0094] Specifically, the valve seat is fixed inside the air duct 32. At the position of the valve seat, the air duct 32 can only be connected through the gas channel 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 channel on the valve seat in a closed state. When the air intake fan 31 drives the outside air into the air duct 32, the incoming airflow acts on the valve core 333, so that the valve core 333 moves relative to the valve seat, thereby realizing the opening of the gas channel, so that the airflow enters the cooking cavity 131 through the air duct 32. When the air intake fan 31 is turned off, there is no outside airflow in the air duct 32, and the force acting on the valve core 333 is released, and the valve core 333 moves relative to the valve seat and closes the gas channel.

[0095] By utilizing the cooperation between the valve core 333 and the valve seat, the one-way conduction of the air guide pipe 32 is effectively achieved. The one-way valve 33 has a simple structure and can effectively reduce the manufacturing cost.

[0096] It should be pointed out that if Fig. 9 As shown, the valve seat includes a first part 331 and a second part 334, wherein the first part 331 and the second part 334 are both cylindrical parts, a bracket with a sliding hole is arranged in the cylinder body of the first part 331, and a limiting ring with a through hole is arranged in the cylinder body of the second part 334, the first part 331 is fixed to the outside of the second part 334 (wherein the fixing method includes but is not limited to clamping, bonding, welding or connecting through a connecting piece, etc.), the first part 331 and the second part 334 surround a gas channel, and the gas channel is connected to the outside through the through hole on the limiting ring, and the valve core 333 is arranged in the gas channel and includes a connecting rod part and a blocking part connected to each other, the connecting rod part is inserted in the sliding hole, and is relatively connected through the connecting part The sliding of the sliding hole allows the blocking part to move toward or away from the limiting ring. When the air intake is closed, the blocking part abuts against the side of the limiting ring facing the bracket and closes the through hole. When the air intake fan 31 passes outside air into the air guide pipe 32, the airflow 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, thereby separating the blocking part from the limiting ring to open the through hole and thereby achieving conduction of the one-way valve 33. When the air intake fan 31 is closed, there is no outside airflow in the air guide pipe 32, and the force acting on the valve core 333 is released. The blocking part and the connecting part slide in the opposite direction relative to the sliding hole of the bracket, thereby causing the blocking part to abut against the limiting ring to close the through hole.

[0097] In some embodiments of the present invention, Fig. 9 As shown, the one-way valve 33 further includes an elastic member 332 , which cooperates with the valve seat and the valve core 333 respectively. The rebound force of the elastic member 332 drives the valve core 333 to have a tendency to close the gas channel.

[0098] 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 air intake fan 31 is running, the valve core 333 moves relative to the valve seat and releases the closure of the gas channel, so that the one-way valve 33 is opened, thereby allowing the outside air to enter the cooking cavity 131 through the air duct 32. After the air intake fan 31 is turned off, the valve core 333 moves relative to the valve seat and closes the gas channel, so that the one-way valve 33 is closed, thereby reducing the backflow of the airflow in the cooking cavity 131.

[0099] The elastic member 332 is matched with the valve core 333 and the valve seat respectively. After assembly, the elastic member 332 is in an elastic deformation state. The elastic member 332 in the elastic deformation state has a rebound force, which acts on the valve core 333, so that the valve core 333 and the valve seat are matched to facilitate the gas passage on the valve seat. By providing the elastic member 332, the valve core 333 has a better closing effect on the gas passage, and the backflow of the airflow in the cooking cavity 131 through the air guide pipe 32 is further reduced.

[0100] It should be understood that the elastic member 332 may be a spring or an elastic sheet, etc.

[0101] In the present application, the elastic member 332 may be a spring, and the valve seat includes a first part 331 and a second part 334, wherein the first part 331 and the second part 334 are both tubular members, a bracket having a sliding hole is arranged in the cylinder body on the first part 331, and a limiting ring having a through hole is arranged in the cylinder body arranged in the second part 334, the first part 331 is sleeved and fixed on the outer side of the second part 334 (wherein, the fixing method includes but is not limited to clamping, bonding, welding or connecting via a connecting piece, etc.), the first part 331 and the second part 334 enclose a gas channel, and the gas channel is connected to the outside through the through hole on the limiting ring, the valve core 333 is arranged in the gas channel and includes a connected connecting rod part and a blocking part, the connecting rod part is penetrated in the sliding hole, and the blocking part can move in a direction close to or away from the limiting ring through the sliding of the connecting part relative to the sliding hole, and when the air intake is closed, the blocking part abuts against the side of the limiting ring facing the bracket and blocks the through hole. The spring is sleeved on the connecting rod part, one end of the spring is against the bracket, and the other end of the spring is against the blocking part. The spring is in a state of elastic deformation and has a rebound force. The rebound force acts on the blocking part, so that the blocking part is against the limit ring, thereby keeping the through hole in a closed state.

[0102] In some embodiments of the present invention, Figures 7 to 9 As shown, the air guide tube 32 includes a vertical section 321, and the one-way valve 33 is arranged in the vertical section 321. The gravity of the valve core 333 and the rebound force of the elastic member 332 drive the valve core 333 to have a tendency to close the gas channel.

[0103] Specifically, the air guide tube 32 includes a vertical section 321, wherein the vertical section 321 is arranged vertically, and the air guide tube 32 is in a structure of bottom air intake (the end connected to the air intake fan 31) and top air outlet (the end connected to the cooking chamber 131) at the position of the vertical section 321, and the one-way valve 33 is arranged in the vertical section 321. The valve body is fixed to the tube wall of the air guide tube 32, the gas channel is formed in the valve body, the valve core 333 is arranged in the gas channel and can move relative to the gas channel, the elastic member 332 is respectively matched with the valve core 333 and the valve seat, the elastic member 332 has a rebound force after being assembled, and the valve core 333 has gravity, and driven by the rebound force and gravity, the valve core 333 keeps the gas channel in a closed state.

[0104] When the air intake fan 31 drives outside air into the air duct 32, the incoming air flow acts on the valve core 333, so that the valve core 333 overcomes its own gravity and the rebound force of the elastic member 332 and moves relative to the valve seat, thereby realizing the opening of the gas passage, so that the air flow enters the cooking chamber 131 through the air duct 32. When the air intake fan 31 is turned off, there is no outside air flow in the air duct 32, the force acting on the valve core 333 is released, and the rebound force of the elastic member 332 and the self-gravity of the valve core 333 drive the valve core 333 to move relative to the valve seat and close the gas passage.

[0105] By setting 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 a state of closing the gas channel, and by cooperating with the elastic member 332, the closing effect of the valve core 333 on the gas channel can be improved, thereby improving the one-way function of the one-way valve 33, and further reducing the backflow of gas in the cooking cavity 131 through the air duct 32.

[0106] It should be pointed out that, in the present application, the air duct 32 also includes a horizontal section 322 , the air intake fan 31 is connected to the vertical section 321 via the horizontal section 322 , and the horizontal section 322 and the vertical section 321 are smoothly transitionally connected.

[0107] In some embodiments of the present invention, the cavity assembly 13 includes a first plate body 137, which constitutes a part of the cooking cavity 131. The first plate body 137 is respectively provided with an air outlet area and an air inlet area. The hot air assembly 50 includes a hot air hood, a heating element and a heating fan. The hot air hood is connected to the first plate body 137 and surrounds a heating cavity. The heating cavity is connected to the cooking cavity 131 through the air inlet area and the air outlet area, respectively. The heating element is arranged in the heating cavity and is located between the air outlet area and the air inlet area. The heating fan includes an impeller, which 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 airflow heated by the heating element enters the cooking cavity 131 through the air inlet area.

[0108] 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, wherein the shape of the cooking cavity 131 includes but is not limited to a rectangle or a sphere, etc.

[0109] In the present application, the cooking cavity 131 is shaped as a rectangular structure, which includes a top wall, a bottom wall, a rear side wall, a left side wall and a right side wall, wherein the first plate body 137 constitutes a portion of the cooking cavity 131, and 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.

[0110] The hot air hood is connected to the side of the first plate 137 facing away from the cooking cavity 131, and the hot air hood and the first plate 137 enclose a heating cavity, the air inlet area (for example, a grid structure or a mesh structure) and the air outlet area (for example, a grid structure or a mesh structure) on the first plate 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 air flows in the air inlet area and the air outlet area do not affect each other), and the heating element and the impeller of the heating fan are both arranged in the heating cavity. In it, the axis of the impeller is coaxially arranged with the air outlet area. In addition, the heating element (quartz tube, metal heating tube or graphite heating tube, etc.) is arranged in a ring 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 flows into the air outlet area, and enters the cooking cavity 131 through the air outlet area to provide hot airflow for the cooking cavity 131.

[0111] It should be understood that, during the process of cooking food, the hot air assembly 50 can operate independently to heat and cook the food in the cooking cavity 131 through the hot air flow.

[0112] When food is being cooked and the steam needs to be discharged, the air intake component 30 and the hot air component 50 are controlled to operate, and the air intake component 30 delivers outside air into the cooking cavity 131. After the outside air enters the cooking cavity 131, it can dilute the steam, and also increase the pressure of the gas in the cooking cavity 131, so that the speed of steam discharge in the cooking cavity 131 is increased. The hot air component 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 impact of steam on the food cooking process, thereby improving the cooking quality of food, and enhancing the user experience.

[0113] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the cavity assembly 13 includes a second plate body 136, which constitutes a part of the cooking cavity 131. The second plate body 136 is connected to or spaced apart from the first plate body 137. An air inlet is opened on the second plate body 136, and the air inlet assembly 30 is connected to the cooking cavity 131 through the air inlet.

[0114] 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, and 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 at an angle or the two are arranged at an interval.

[0115] Among them, a hot air assembly 50 is provided on the side of the first plate 137 away from the cooking cavity 131, and the hot air cover and the side of the first plate 137 away from the cooking cavity 131 enclose a hot air cavity, and the hot air cavity is connected with the cooking cavity 131 through the air inlet area and the air outlet area on the first plate 137. The impeller of the heat dissipation fan 21 is coaxially arranged with the air outlet area, and the heating element is arranged on the radial outer side 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 flows into the air outlet area, and enters the cooking cavity 131 through the air outlet area to provide hot airflow for the cooking cavity 131.

[0116] One end of the air duct 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 duct 32 is connected to the connecting 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 intake fan 31 is running, the 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.

[0117] By arranging the air flow inlet on the second plate 136 , the air flow interference of the air flow from the air flow inlet on the air inlet area and the air outlet area on the first plate 137 is reduced, thereby reducing the adverse effect on the air flow in the cooking cavity 131 .

[0118] In some embodiments of the present invention, the cooking appliance 100 further includes a heating component, which is connected to the cavity component 13 and is used to heat the food in the cooking cavity 131 .

[0119] Specifically, the heating component includes but is not limited to a microwave heating device, a heat radiation device, and a high-temperature steam generating device. When heating food, the heating component can be operated to heat the food in the cooking cavity 131, thereby effectively cooking the food.

[0120] In some embodiments of the present invention, the exhaust assembly 40 includes an exhaust pipe 42 and an air guide hood 41, one end of the exhaust pipe 42 is connected to the cooking cavity 131, the inlet of the air guide hood 41 is connected to the other end of the exhaust pipe 42, and the outlet of the air guide hood 41 is connected to the outside.

[0121] Specifically, during the cooking process, steam is generated in the cooking cavity 131, and the steam enters the air guide 41 through the exhaust pipe 42, and finally the steam is uniformly discharged through the air guide 41. By providing the exhaust pipe and the air guide 41, the discharge of the steam is guided, so that the steam is discharged along a preset path, which reduces the situation where the steam does not need to be discharged, causing burns to users or damage to components such as cabinets.

[0122] 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 and the second plate body 136 are connected at an angle or are arranged at intervals, the hot air assembly 50 is connected to the first plate body 137 and is connected to the cooking cavity 131, and the exhaust assembly 40 is connected to the second plate body 136 and is connected to the cooking cavity 131.

[0123] 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, and 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 at an angle or the two are arranged at an interval.

[0124] Among them, a hot air assembly 50 is provided on the side of the first plate 137 away from the cooking cavity 131, and the hot air cover and the side of the first plate 137 away from the cooking cavity 131 enclose a hot air cavity, and the hot air cavity is connected with the cooking cavity 131 through the air inlet area and the air outlet area on the first plate 137. The impeller of the heat dissipation fan 21 is coaxially arranged with the air outlet area, and the heating element is arranged on the radial outer side 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 flows into the air outlet area, and enters the cooking cavity 131 through the air outlet area to provide hot airflow for the cooking cavity 131.

[0125] 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 communicates with the cooking cavity 131, and the other end of the exhaust pipe 42 is connected to the air guide cover 41, so that the cooking cavity 131 is connected to the air guide cover 41 through the exhaust pipe 42, and is connected to the outside through the air guide cover 41. By arranging the exhaust assembly 40 and the hot air assembly 50 on different plates, the airflow interference of the hot air assembly 50 on the exhaust assembly 40 is reduced, so that the exhaust assembly 40 can effectively exhaust the cooking cavity 131, so as to improve the exhaust effect.

[0126] One end of the air duct 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 duct 32 is connected to the connection structure on the second plate 136, so that the air duct 32 is connected to the air flow inlet on the second plate 136. When the air intake fan 31 is running, the 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. By arranging the air flow inlet on the second plate 136, the air flow interference of the air flow in the air flow inlet with the air intake area and the air outlet area on the first plate 137 is reduced, thereby affecting the adverse effect on the air flow in the cooking cavity 131.

[0127] In some embodiments of the present invention, the cooking appliance 100 also includes a control component, which includes a temperature collecting component, a humidity collecting component and a control device. The temperature collecting component is arranged in the cooking cavity 131 and is used to collect the temperature in the cooking cavity 131. The humidity collecting component is arranged in the cooking cavity 131 and is used to collect the humidity in the cooking cavity 131. The control device is electrically connected to the temperature collecting component, the humidity collecting component, the air intake component 30 and the hot air component 50, respectively.

[0128] Specifically, the stable collection component and the humidity collection component respectively collect the temperature and humidity in the cooking cavity 131, and the control device controls the air intake component 30 and the hot air component 50 according to the collected 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 food.

[0129] It should be pointed out that, in the present application, the temperature collection component is a temperature sensor, and the humidity collection component is a humidity sensor.

[0130] In some embodiments of the present invention, Figure 1 and then Figure 2As shown, 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 duct 121. The heat dissipation duct 121 is arranged on the outside of the cooking cavity 131 and is not connected with the cooking cavity 131. The heat dissipation duct 121 includes an air flow inlet and an air flow outlet. The air flow inlet is connected to the outside. The electrical component 20 is arranged in the heat dissipation 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 duct 121 through the air flow inlet and exchange heat with the functional device group 22, and to drive the air after heat exchange with the functional device group 22 to flow out through the air flow outlet. The exhaust component 40 includes an air guide cover 41, which is installed on the body 10 and includes an air inlet and an air outlet. The air inlet is respectively connected to the air flow outlet and the cooking cavity 131, and the air outlet is connected to the front side of the body 10.

[0131] Specifically, the power device group in the electrical components includes but is not limited to a controller, a circuit board, a transformer, an inverter, and a magnetron, etc. When the cooking appliance 100 is in operation, the power device group generates heat. In order to maintain the operating temperature of the power device group at a desired temperature condition, the heat dissipation fan 21 operates to allow external air to enter the heat dissipation duct 121. The airflow entering the heat dissipation 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 airflow after heat exchange with the power device group is discharged through the heat dissipation duct 121.

[0132] The exhaust component 40 includes an air guide hood 41, and the heat dissipation air duct 121 and the cooking cavity 131 are respectively connected with the recessed air inlet 412. The airflow discharged from the heat dissipation air duct 121 enters the air guide hood 41 and is discharged through the air outlet 411 of the air guide hood 41. When the airflow flows from the air inlet 412 of the air guide hood 41 to the air outlet 411, negative pressure is generated at the connection position between the air guide hood 41 and the cooking cavity 131. Under the influence of the negative pressure, the air guide hood 41 will produce a suction effect on the cooking cavity 131, thereby increasing the discharge rate of steam in the cooking cavity 131 and allowing the steam in the cooking cavity 131 to be discharged quickly.

[0133] During the cooking process, the steam in the cooking cavity 131 enters the air duct 41 through the air inlet of the air duct 41, and the heat dissipation fan 21 is running, so that the outside air flows into the heat dissipation duct 121 through the air inlet of the heat dissipation duct 121 and exchanges heat with the functional device group 22. The air after heat exchange flows out through the air flow and enters the air duct 41 through the air inlet of the air duct 41 and mixes with the steam in the air duct 41, and finally is discharged through the exhaust port. Since the exhaust port is connected to the front side of the body 10 (in this application, the side of the cooking utensil 100 facing the user is the front side), the front side discharge of the steam is realized, thereby reducing the adverse effects of the steam on the cabinet. At the same time, the heat dissipation duct 121 is connected to the air duct 41, so that the heat dissipation airflow can be mixed with the whole, thereby reducing the temperature of the steam, and thus reducing the situation of steam scalding the user.

[0134] In some embodiments of the present invention, Figure 5 , Figure 6 , Fig.10 and Fig.11 As 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 .

[0135] Specifically, the cooking cavity 131 is connected to the air guide cover 41 through the exhaust pipe 42, wherein one end of the exhaust pipe 42 is connected to the connection part of the cavity assembly 13 (such as a plug or other structure, and the connection method of the exhaust pipe 42 and the connection part includes but is not limited to plugging or connecting via a connector), 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 of the air guide pipe 32 and the air guide cover 41 includes but is not limited to plugging or connecting via a connector). By providing the exhaust pipe 42, the air guide cover 41 can be effectively connected to the cooking cavity 131, so that the air guide cover 41 can be reasonably laid out and installed, thereby improving the overall compactness of the structure.

[0136] The exhaust pipe 42 is a flexible pipe (such as a rubber or silicone pipe, etc.), which is easy to set up and install, and can effectively improve the convenience of assembly, thereby effectively improving the rhythm of production and improving the efficiency of production. Setting the exhaust pipe 42 as a flexible pipe can make the exhaust pipe 42 smoothly transition at the turning position, thereby reducing the obstruction to the airflow, and further reducing the impact on the flow rate of the airflow.

[0137] In some embodiments of the present invention, Figure 3 As 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] In this way, the ratio of the opening area of ​​the air inlet 132 to the opening area of ​​the exhaust hole 133 is set to 2:1, so that a micro-pressure gas field can be formed in the cooking cavity 131, which can increase the steam discharge rate while reducing the adverse effects of the pressure increase on the cooking process, thereby effectively improving the cooking quality of food.

[0145] It should be pointed out 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 reduced in the direction from the cooking cavity 131 to the air guide cover 41.

[0146] In some embodiments of the present invention, Fig.10 and Fig.11 As shown, the exhaust pipe 42 includes a first pipe section 421 and a second pipe section 422 connected to each other. 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 greater than the diameter of the second pipe section 422.

[0147] Specifically, by setting the first pipe segment 421 and the second pipe segment 422, and setting the diameter of the first pipe segment 421 and the diameter of the second pipe segment 422 respectively, the flow cross-section of the exhaust pipe 42 in the direction from the cooking cavity 131 to the air guide cover 41 is reduced, and then when the airflow flows from the first pipe segment 421 to the second pipe segment 422, the flow cross-section is reduced, so that the pressure of the airflow is increased, thereby increasing the flow velocity of the airflow, so that the airflow can increase the discharge rate.

[0148] In some embodiments of the present invention, the ratio of the diameter of the first tube segment 421 to the diameter of the second tube segment 422 is 3:2.

[0149] In this way, 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 storage structure can be formed in the exhaust pipe 42, which can reduce the impact on the air flow while increasing the steam exhaust rate, thereby further improving the steam exhaust effect.

[0150] In some embodiments of the present invention, Figure 3 , Fig.10 and Fig.11 As shown, along the direction from the air inlet to the air outlet, the flow cross-section of the air guide cover 41 is reduced.

[0151] Specifically, the air inlet 412 of the air guide hood 41 is respectively connected to the heat dissipation duct 121 and the cooking cavity 131. The airflow in the heat dissipation duct 121 and the steam in the cooking cavity 131 both enter the air guide hood 41. The flow cross-section of the air guide hood 41 is set to be reduced along the direction from the air inlet 412 to the exhaust port 411, so that the steam and the airflow discharged from the heat dissipation duct 121 can be evenly mixed, thereby reducing the temperature of the exhaust gas. At the same time, the flow cross-section is reduced, which increases the pressure of the airflow, thereby increasing the flow velocity of the airflow, so that the airflow can be discharged at a higher rate.

[0152] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the machine 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 panel 134. The front panel 134 is provided with a take-in / take-out opening 1341. The take-in / take-out opening 1341 is communicated with the cooking cavity 131. The cavity assembly 13 is mounted on the top of the base assembly 12. The heat dissipation duct 121 is formed on the base assembly 12. The door assembly 11 is connected to the front panel 134 and is used to open or close the take-in / take-out opening 1341. When the door assembly 11 closes the take-in / take-out 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, the door assembly 11 and the base assembly 12 have a separation space 14. The exhaust port of the air guide cover 41 is communicated with the separation space 14.

[0153] Specifically, by setting the exhaust port 411 of the air guide cover 41 to be in communication with the partition space 14, the steam exhaust position can be hidden, thereby improving the appearance coordination of the whole machine.

[0154] In addition, when the steam is discharged through the exhaust port 411 of the air guide hood 41 and enters the partition space 14, the steam can come into contact with the outside air when flowing along the partition space 14, further reducing the temperature of the steam and further reducing the occurrence of accidents involving users.

[0155] In some embodiments of the present invention, the air inlet of the heat dissipation duct 121 is opened at the bottom of the base assembly 12 .

[0156] Specifically, by opening the air flow inlet of the heat dissipation duct 121 at the bottom of the base assembly 12, the structure of air intake at the bottom of the heat dissipation duct 121 is realized, thereby reducing the situation where external foreign matter enters the heat dissipation duct 121 through the air flow inlet, thereby reducing the occurrence of power device group failure caused by foreign matter entering the heat dissipation duct 121.

[0157] It should be pointed out that in the present application, the base assembly 12 includes a base body and a water box, the cavity assembly 13 is fixed on the base body, the heat dissipation duct 121 is formed on the base body, and the air guide cover 41, the power device group and the heat dissipation fan 21 are all installed on the base body. In this way, the base body can be used to install the air guide cover 41, the power device group and the heat dissipation fan 21, thereby reducing 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 can improve the space utilization rate of the whole machine.

[0158] The power device group is arranged on the base body, which can reduce the adverse effect of the heat in the cooking cavity 131 during cooking on the power device group, thereby reducing the failure rate of the cooking appliance 100.

[0159] 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 utensil 100, thereby reducing the damage to the cabinets and other components caused by the heat being transferred to the cabinets through the base body.

[0160] In addition, the water box is set on the base body in a pull-out manner. The water box is set at the front end of the base and is flush with the door assembly 11 (when the door assembly 11 is closed). The water box includes a clean water chamber and a waste water chamber, wherein the clean water chamber is connected to the high-temperature steam device of the power device group.

[0173] Specifically, when the current humidity in the cooking cavity 131 is greater than the preset humidity 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 air intake fan 31 of the air intake component 30, the heating element of the hot air component 50 and the heating fan of the hot air component 50 to operate, thereby achieving rapid discharge of steam in the cooking cavity 131 to reduce the impact on the cooking quality of food.

[0174] S50: According to the current temperature being greater than the preset temperature value, the heating element is controlled to be turned off.

[0175] Specifically, during the discharge of steam from the cooking cavity 131, the heating fan and the heating element of the hot air assembly 50 are both running. At this time, the hot air assembly 50 provides a hot air flow into the cooking cavity 131. When the current temperature in the cooking cavity 131 is greater than the preset temperature 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 lowered. Based on this, the control device controls the heating element to turn off and keep the heating fan running, so that the temperature in the cooking cavity 131 meets the cooking requirements while achieving rapid discharge of steam in the cooking cavity 131, thereby reducing the impact on the cooking quality of food.

[0176] S60: According to the current humidity being less than or equal to the preset humidity value, the air intake fan 31 and the heating fan are controlled to be turned off.

[0177] Specifically, during the steam discharge process of the cooking cavity 131, when the current humidity of the cooking cavity 131 is less than or equal to the humidity preset value, it indicates that the humidity in the cooking cavity 131 meets the cooking requirements. Further steam discharge operation will cause the food to become hard and dry after cooking. Therefore, the control device controls the air intake fan 31 and the heating fan to turn off to improve the cooking quality of the food.
