[0086] In the related art, cooking appliances either have only a single baking function, for example, an oven. Cooking appliances either have only a single steaming function, such as a steamer. A cooking appliance capable of baking is difficult to steam food, and a cooking appliance capable of steaming food is difficult to bake food. Therefore, cooking appliances have a single function and it is difficult to balance steaming and baking of food.
[0087] First Embodiment
[0088] A cooking appliance provided by an embodiment of the present application, please refer to Figures 1 to 5 , the cooking appliance includes a cooking container 1, a first heater 2, a first heater 2 and a pressure limiting valve 4. The cooking container 1 has a cooking cavity 11 and an exhaust passage for exhausting the gas in the cooking cavity 11. The first heater 2 is located at the bottom of the cooking cavity 11, and the first heater 2 is installed on the cooking container 1. The first heater 2 is located at the top of the cooking cavity 11, and the second heater 3 is installed on the cooking container 1. The pressure limiting valve 4 is installed on the cooking container 1 to open or close the exhaust passage.
[0089] Exemplarily, the diameter of the exhaust passage is greater than or equal to 10 mm, or the cross-sectional area of the exhaust passage is greater than or equal to 80 mm 2 .
[0090] Exemplarily, the cross-sectional area of the exhaust passage is greater than or equal to 80 mm 2 , and the cross-sectional area of the exhaust passage is greater than or equal to 300 mm 2 .
[0091] When the pressure in the cooking cavity 11 is greater than the pressure limit value of the pressure limiting valve 4, the gas in the cooking cavity 11 pushes open the pressure limiting valve 4 and is discharged outward through the exhaust passage.
[0092] When the pressure in the cooking cavity 11 is less than the pressure limit value of the pressure limiting valve 4, the gas in the cooking cavity 11 will not be discharged outward.
[0093] Exemplarily, the pressure limit value of the pressure limiting valve 4 can be set relatively small. On the one hand, there is a certain pressure in the cooking cavity 11, which can lock the moisture of the food and reduce the evaporation of the food moisture when the pressure limiting valve 4 is not opened. On the other hand, the discharge of steam reduces the food moisture, which is beneficial to baking.
[0094] Exemplarily, the pressure limit value of the pressure limiting valve 4 is less than or equal to 5 kPa.
[0095] Exemplarily, the pressure limit value of the pressure limiting valve 4 is greater than or equal to 1, and the pressure limit value of the pressure limiting valve 4 is less than or equal to 5 kPa.
[0096] Exemplarily, please refer to Figure 4 , the top-bottom direction in the figure is the direction shown by the arrow R1 in the figure.
[0097] In the embodiments of the present application, the food in the cooking cavity 11 is heated by the first heater 2 and / or the second heater 3. The steam generated during the cooking process can be discharged through the pressure limiting valve 4, reducing the possibility of excessive pressure in the cooking cavity 11. Through the heating of the first heater 2 and the second heater 3 and the exhaust of the pressure limiting valve 4, the food in the cooking cavity 11 can be steamed well. During the process of roasting food, the food is heated jointly by the first heater 2 at the bottom and the second heater 3 at the top, so that both the bottom and the top of the food can be roasted more evenly, reducing the possibility that the top or the bottom of the food is over-roasted, and thus the food can be roasted well.
[0098] In one embodiment, please refer to Figures 1 to 5 , the second heater 3 is located inside the cooking cavity 11.
[0099] In the embodiments of the present application, the second heater 3 is at the top of the cooking cavity 11. During the cooking process, the food hardly contacts the second heater 3. The second heater 3 located inside the cooking cavity 11 can reduce the heat dissipation of the second heater 3 to the outside, and the second heater 3 can fully heat the food.
[0100] It can be understood that the position of the second heater 3 is not limited. Exemplarily, the second heater 3 can be arranged outside the cooking cavity 11.
[0101] In one embodiment, please refer to Figures 1 to 5 , the cooking container 1 includes a cooking main body 13 and a container cover 14. The container cover 14 and the cooking main body 13 enclose the cooking cavity 11. The second heater 3 is installed on the container cover 14, and the exhaust passage is formed on the container cover 14.
[0102] The container cover 14 is covered on the cooking main body 13. Opening the container cover 14 can enable taking and placing food in the cooking cavity 11.
[0103] Exemplarily, the container cover 14 is square.
[0104] In the embodiments of the present application, the second heater 3 is installed on the container cover 14, so that the second heater 3 can move with the container cover 14 during the process of opening and closing the container cover 14. When the opened container cover 14 is moved away from the opening of the cooking cavity 11 in the cooking main body 13, the second heater 3 is correspondingly moved away from the opening of the cooking cavity 11 in the cooking main body 13, reducing the interference of the second heater 3 to the taking and placing of food. When the container cover 14 is closed, the second heater 3 follows the container cover 14 and moves back to the top of the cooking cavity 11, facilitating better heating of the food.
[0105] It can be understood that the position of the second heater 3 is not limited. Exemplarily, the second heater 3 can be installed on the cooking main body 13.

[0108] In the embodiment of the present application, the cooking cavity 11 is enclosed by the first lid 141 and the cooking main body 13, and the second heater 3 is installed on the first lid 141, so that the installation of the second heater 3 located in the cooking cavity 11 is more convenient. The second lid 142 is connected to a side of the first lid 141 facing away from the cooking cavity 11, and the possibility of the user being directly in contact with the relatively hot first lid 141 and being scalded is reduced by the separation of the second lid 142. The exhaust passage straddles the first lid 141 and the second lid 142, and the steam in the cooking cavity 11 can be discharged outward through the exhaust passage via the first lid 141 and the second lid 142.
[0109] It can be understood that the specific structure of the container lid 14 is not limited. Exemplarily, the second lid 142 may not be provided, and the second heater 3 is installed on the first lid 141. Exemplarily, the second heater 3 may be provided on the second lid 142.

[0210] The third embodiment
[0211] The embodiment of the present application provides a cooking appliance, please refer toFigures 17 to 21 , the cooking appliance includes a cooking main body 1, a container lid 14 and a pressure limiting valve 4. The cooking main body 1 has a cooking cavity 11. The container lid 14 covers the cooking cavity 11. The container lid 14 has an exhaust port 121 communicating with the cooking cavity 11. The pressure limiting valve 4 covers the exhaust port 121, and the pressure limiting valve 4 is of a hollow structure.
[0212] Exemplarily, the container lid 14 is located above the cooking main body 1, and the pressure limiting valve 4 covers above the exhaust port 121.
[0213] Exemplarily, the diameter of the exhaust port 121 is greater than or equal to 10 mm, or the cross-sectional area of the exhaust port 121 is greater than or equal to 80 mm 2 .
[0214] Exemplarily, the cross-sectional area of the exhaust port 121 is greater than or equal to 80 mm 2 , and the cross-sectional area of the exhaust port 121 is less than or equal to 300 mm 2 .
[0215] It can be understood that the shape of the exhaust port 121 is adapted to the cross-sectional shape of the pressure limiting valve 4.
[0216] In the embodiment of the present application, the pressure limiting valve 4 covers the exhaust port 121. When the pressure in the cooking cavity 11 is small, the pressure limiting valve 4 seals the exhaust port 121 to limit the steam discharge in the cooking cavity 11. During the cooking process, the steam in the cooking cavity 11 continuously increases, and the pressure in the cooking cavity 11 increases. When the pressure in the cooking cavity 11 increases to a set value, the thrust of the steam received by the pressure limiting valve 4 is greater than the gravity, and the steam in the cooking cavity 11 will lift the hollow pressure limiting valve 4. The pressure limiting valve 4 opens, so that the exhaust port 121 can discharge the steam in the cooking cavity 11, reducing the pressure in the cooking cavity 11; when the pressure in the cooking cavity 11 drops to the set value, the pressure limiting valve 4 drops and covers the exhaust port 121 again, and the pressure limiting valve 4 closes, making the exhaust port 121 hardly able to discharge steam. On the premise that the hollow structure of the pressure limiting valve 4 can block the exhaust port 121 with sufficient volume, the hollow structure of the pressure limiting valve 4 is lighter in weight, and the opening pressure of the pressure limiting valve 4 is small, so that a relatively small pressure can be maintained in the cooking cavity 11 during the cooking process. The pressure limiting valve 4 is light in weight and large in volume, and the size of the adapted exhaust port 121 can be made relatively large accordingly, realizing large-area exhaust, quickly discharging the gas in the cooking cavity 11, and reducing the pressure in the cooking cavity 11. When the cooking appliance is in a non-pressure cooking situation, large-area exhaust can achieve the same pressure inside and outside the cooking cavity 11.
[0217] In one embodiment, please refer to Figures 17 to 21 , the exhaust port 121 is circular, the pressure limiting valve 4 is a hollow sphere, the pressure limiting valve 4 is supported on the hole wall 918 of the exhaust port 121, and the diameter of the pressure limiting valve 4 is greater than the diameter of the exhaust port 121.
[0218] In the embodiment of the present application, under the action of steam, the pressure limiting valve 4 can continuously rotate and jump on the exhaust port 121 to open and close the valve. In this case, the contact surface between the spherical pressure limiting valve 4 and the hole wall 918 of the exhaust port 121 is always circular, and the spherical pressure limiting valve 4 can seal the circular exhaust port 121 as much as possible.
[0219] It can be understood that the shape of the exhaust port 121 is not limited to being circular, and the pressure limiting valve 4 is not limited to being a hollow sphere. Exemplarily, the pressure limiting valve 4 is a hollow ellipsoid, and the shape of the exhaust port 121 is adapted to the cross-sectional shape of the pressure limiting valve 4.
[0220] Exemplarily, the pressure limiting valve 4 is a hollow cube, and the shape of the exhaust port 121 is square.
[0221] In one embodiment, please refer to Figures 17 to 21 , the pressure limiting valve 4 includes a first housing 41 and a second housing 42 connected to each other. The outer surfaces of the first housing 41 and the second housing 42 are both spherical caps, and the outer surfaces of the first housing 41 and the second housing 42 are located on the same spherical surface.
[0222] In the embodiment of the present application, the pressure limiting valve 4 is divided into a first housing 41 and a second housing 42. After the first housing 41 and the second housing 42 are respectively manufactured and then connected, it is convenient to manufacture the pressure limiting valve 4 into a hollow sphere.
[0223] It can be understood that the outer surfaces of the first housing 41 and the second housing 42 are not limited to being spherical caps. Exemplarily, the outer surface of the first housing 41 is a spherical cap, and the first housing 41 has an opening. The second housing 42 is a plug, and the second housing 42 closes the opening of the first housing 41. During the manufacturing process of the hollow sphere, a spherical core is first manufactured, the core is placed in a spherical mold, and then the mold is closed and cast to obtain the first housing 41. The first housing 41 has an opening for removing the core after casting, and then the second housing 42 is used to close the opening of the first housing 41.
[0224] In one embodiment, please refer to Figures 17 to 21 , the pressure limiting valve 4 includes a first housing 41 and a second housing 42 connected to each other, and the weight of the first housing 41 is greater than the weight of the second housing 42.
[0225] It can be understood that the shape of the exhaust port 121 is adapted to the cross-sectional shape of the first housing 41.
[0226] Exemplarily, the exhaust port 121 is circular, the shape of the first housing 41 is a semi-sphere, and the shape of the second housing 42 is not limited.
[0227] In the embodiment of the present application, the weight of the first shell 41 is greater than that of the second shell 42, so that the center of gravity of the pressure limiting valve 4 deviates from the center of the sphere, and the center of gravity of the pressure limiting valve 4 is biased toward the first shell 41. During the rotation and jumping of the pressure limiting valve 4, the pressure limiting valve 4 is under the action of gravity, so that the heavier first shell 41 will be located at the bottom, and the first shell 41 is always in contact with the hole wall 918 of the exhaust port 121. The pressure limiting valve 4 can automatically correct the position of contact with the exhaust port 121 to avoid the situation where the joint between the first shell 41 and the second shell 42 may not be firmly sealed to the exhaust port 121.
[0228] It is understood that the weight of the first housing 41 is not limited to be greater than the weight of the second housing 42. Exemplarily, the weight of the first housing 41 is equal to the weight of the second housing 42.
[0229] In one embodiment, please refer to Figures 17 to 21 The first shell 41 and the second shell 42 are welded, and the distance from the first shell 41 to the weld 43 is equal to the distance from the second shell 42 to the weld 43 .
[0230] It should be noted that the distance from the first shell 41 to the weld 43 refers to the maximum distance from the first shell 41 to the weld 43. The distance from the second shell 42 to the weld 43 refers to the maximum distance from the second shell 42 to the weld.
[0231] Exemplarily, when the first shell 41 and the second shell 42 are two hemispherical caps, the outer diameter of the first shell 41 is equal to the outer diameter of the second shell 42, and the distance from the first shell 41 to the weld 43 is equal to the distance from the second shell 42 to the weld 43, both of which are the radius of the first shell 41 or the second shell 42.
[0232] In the embodiment of the present application, the welding point of the outer surface of the first shell 41 and the second shell 42 can be made relatively smooth, reducing the unevenness of the outer surface of the pressure limiting valve 4 and reducing the gap between the pressure limiting valve 4 and the exhaust port 121.
[0233] It is understandable that the distance from the first shell 41 to the weld 43 is not limited to be equal to the distance from the second shell 42 to the weld 43. Exemplarily, the distance from the first shell 41 to the weld 43 is greater than the distance from the second shell 42 to the weld 43.
[0234] In one embodiment, please refer to Figures 17 to 21 The outer surface of the first shell 41 and the outer surface of the second shell 42 are both spherical caps, and the outer surface of the first shell 41 and the outer surface of the second shell 42 are located on the same spherical surface.
[0235] It can be understood that the outer surface area of the first shell 41 is equal to the outer surface area of the second shell 42 .
[0236] In the embodiments of the present application, the outer shapes of the first housing 41 and the second housing 42 can be made relatively close, which is convenient for manufacturing the first housing 41 and the second housing 42. The welding position of the first housing 41 and the second housing 42 is at the maximum diameter of the spherical ball, which is also convenient for welding the first housing 41 and the second housing 42.

[0267] The up - and - down direction is the direction indicated by the arrow R2.
[0268] A cooking appliance provided by the embodiments of the present application, please refer to Figures 22 to 31 , including a cooking container 1, a pressure - limiting valve 4, and a temperature detector 940. The interior of the cooking container 1 has a working space 919, and the working space 919 includes a cooking cavity 11 and an installation cavity 919, an exhaust cavity 920, and an exhaust port 121 that are connected in sequence. The pressure - limiting valve 4 is located in the working space 919, and at least part of the pressure - limiting valve 4 is located in the installation cavity 919. The pressure - limiting valve 4 is used to connect or cut off the installation cavity 919 and the cooking cavity 11. The temperature detector 940 is at least partially located in the exhaust cavity 920, and the fluid in the exhaust cavity 920 flows through the temperature detector 940 to the exhaust port 121. The arrangement direction of the pressure - limiting valve 4 and the temperature sensor is the preset direction, and the exhaust cavity 920 extends from the pressure - limiting valve 4 to the temperature detector 940 along the preset direction.
[0269] When the pressure in the cooking cavity 11 is greater than or equal to the pressure - limiting value of the pressure - limiting valve 4, the pressure - limiting valve 4 opens, and the steam in the cooking cavity 11 flows through the pressure - limiting valve 4, through the installation cavity 919 and the exhaust cavity 920, to the exhaust port 121.
[0270] When the pressure in the cooking cavity 11 is less than the pressure - limiting value of the pressure - limiting valve 4, the pressure - limiting valve 4 closes, and the steam in the cooking cavity 11 is basically sealed in the cooking cavity 11 by the pressure - limiting valve 4.
[0271] Exemplarily, the pressure - limiting value of the pressure - limiting valve 4 is less than or equal to 5 kPa.
[0272] Exemplarily, the pressure - limiting value of the pressure - limiting valve 4 is less than or equal to 5 kPa, and the pressure - limiting value of the pressure - limiting valve 4 is greater than or equal to 1 kPa.
[0273] Exemplarily, the diameter of the exhaust port 121 is greater than or equal to 10 mm, or the cross-sectional area of the exhaust port 121 is greater than or equal to 80 mm 2 .
[0274] Exemplarily, the cross-sectional area of the exhaust port 121 is greater than or equal to 80 mm 2 , and the cross-sectional area of the exhaust port 121 is less than or equal to 300 mm 2 .
[0275] In the embodiment of the present application, the working space 919 is located inside the cooking container 1, the pressure limiting valve 4 is located in the working space 919, and there is almost no installation gap communicating with the outside between the pressure limiting valve 4 and the cooking container 1, reducing the leakage of steam. When the pressure in the cooking cavity 11 is greater than the pressure limiting value of the pressure limiting valve 4, the steam in the cooking cavity 11 passes through the pressure limiting valve 4 and is discharged through the installation cavity 919, the exhaust cavity 920, and the exhaust port 121 in sequence. Since the temperature measuring device 940 is in the exhaust cavity 920, the steam discharged to the exhaust port 121 through the pressure limiting valve 4 can flow through the temperature measuring device 940 in the exhaust cavity 920 as much as possible, which is beneficial to increasing the amount of steam flowing through the temperature measuring device 940. Furthermore, the exhaust cavity 920 extends from the pressure limiting valve 4 to the temperature measuring device 940 along the preset direction, and the exhaust cavity 920 extends almost linearly, reducing the flow resistance of the steam in the exhaust cavity 920, reducing the large energy loss of the steam flow, reducing the contact time and heat exchange between the steam and the pipe wall surface, which is beneficial to suppressing the formation of condensed water during the flow of the steam in the exhaust cavity 920, and increasing the amount of steam flowing to the temperature measuring device 940. Since the situation where the amount of steam flowing to the temperature measuring device 940 is reduced due to leakage and the formation of condensed water is better suppressed, the amount of steam flowing to the temperature measuring device 940 is increased, so that the steam temperature measured by the temperature measuring device 940 is more accurate.

The opening and closing of the pressure limiting valve 4 is achieved by the movement of the valve body 938 within the space defined by the valve seat 931 and the valve cover 936.

[0298] Exemplarily, the second cavity 939 may be absent, the valve cover 936 partially extends into the cooking cavity 11 , the valve seat 931 is sleeved on the outside of the valve cover 936 , and the connection port between the first cavity 932 and the cooking cavity 11 is opened or closed by the valve body 938 .

The valve body 938 can be opened and closed by the pressure-limiting valve 4 with a smaller thickness along the arrangement direction of the first cavity 932 and the second cavity 939, thereby reducing space occupancy and improving space utilization.
