DETAILED DESCRIPTION

[0091] It should be noted that the embodiments and technical features in the present disclosure can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as an explanation and illustration of the present disclosure, and should not be regarded as an improper limitation of the present disclosure.

[0092] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The terms "first" and "second" in the embodiments of the present disclosure are merely to distinguish similar objects, and do not represent a specific order of the objects. Understandably, "first" and "second" can be interchanged in a specific order or sequence as allowed, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0093] In the related art, a cooking appliance has only a single baking function, such as an oven. A cooking appliance has only a single steaming function, such as a steamer. A cooking appliance capable of baking is difficult to steam food. A cooking appliance capable of steaming food is difficult to bake food. Therefore, a cooking appliance has a single function and is difficult to steam and bake food.

[0094] First embodiment

[0095] A cooking appliance provided by the embodiments of the present disclosure, please refer to FIG. 1-5, 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 discharging 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 second heater 3 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.

[0096] When the pressure in the cooking cavity 11 is greater than the pressure limiting 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.

[0097] When the pressure in the cooking cavity 11 is less than the pressure limiting value of the pressure limiting valve 4, the gas in the cooking cavity 11 will not be discharged outward.

[0098] Exemplarily, the pressure limiting value of the pressure limiting valve 4 can be set to be small, on the one hand, there is a certain pressure in the cooking cavity 11, which can lock the moisture of the food when the pressure limiting valve 4 is not opened, reducing the evaporation of the moisture of the food, on the other hand, the steam discharge reduces the moisture of the food, which is beneficial to baking.

[0099] Exemplarily, the pressure limiting value of the pressure limiting valve 4 is less than or equal to 5kPa.

[0100] Exemplarily, the pressure limiting value of the pressure limiting valve 4 is greater than or equal to 1kPa, and the pressure limiting value of the pressure limiting valve 4 is less than or equal to 5kPa.

[0101] Exemplarily, please refer to FIG. 4, the top-bottom direction in the figure is the direction indicated by the arrow R1 in the figure.

[0102] In the embodiments of the present disclosure, the food in the cooking cavity 11 is heated by the first heater 2 and / or the second heater 3, and the steam generated in the cooking process can be discharged through the pressure limiting valve 4, so as to reduce 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 better steamed. In the process of baking food, the food is heated by the first heater 2 at the bottom and the second heater 3 at the top, so that the bottom and the top of the food can be baked more uniformly, reducing the possibility of over-baking the top or bottom of the food, thereby better baking the food.

[0103] In an embodiment, 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 .

[0104] Exemplarily, the diameter of the exhaust passage is 10 mm, 15 mm, 20 mm, 25 mm or 30 mm.

[0105] Exemplarily, the cross-sectional area of the exhaust passage is 80 mm 2 , 100 mm 2 , 180 mm 2 , 200 mm 2 , 250 mm 2 , or 300 mm 2 .

[0106] 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 .

[0107] 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 less than or equal to 300 mm 2 .

[0108] In the embodiments of the present disclosure, 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 , and the size of the exhaust passage is more appropriate, which can accelerate the discharge of steam and avoid excessive pressure in the cooking cavity 11 due to the gas generated in the cooking cavity 11 not being discharged in time.

[0109] In an embodiment, the pressure limiting value of the pressure limiting valve 4 is less than or equal to 5 kPa.

[0110] Exemplarily, the pressure limiting value of the pressure limiting valve 4 is greater than or equal to 1 kPa.

[0111] Exemplarily, the pressure limiting value of the pressure limiting valve 4 is 1 kPa, 2 kPa, 3 kPa, 4 kPa or 5 kPa.

[0112] In the embodiments of the present disclosure, the pressure limiting value of the pressure limiting valve 4 is less than or equal to 5 kPa, which is more appropriate, and is conducive to maintaining the pressure in the cooking cavity 11 in an appropriate range and accelerating the ripening of food in the cooking cavity 11.

[0113] In an embodiment, referring to FIGS. 1-5, the second heater 3 is located in the cooking cavity 11.

[0114] In the embodiments of the present disclosure, the second heater 3 is located at the top of the cooking cavity 11, and food is almost not in contact with the second heater 3 during cooking. The second heater 3 located in the cooking cavity 11 can reduce heat dissipation of the second heater 3 to the outside, which is conducive to the second heater 3 to heat the food sufficiently.

[0115] It can be understood that the position of the second heater 3 is not limited. For example, the second heater 3 can be arranged outside the cooking cavity 11.

[0116] In an embodiment, referring to FIGS. 1-5, the cooking container 1 includes a cooking body 13 and a container cover 14. The container cover 14 and the cooking body 13 surround the cooking cavity 11, the second heater 3 is installed on the container cover 14, and the exhaust passage is formed in the container cover 14.

[0117] The container cover 14 covers the cooking body 13, and opening the container cover 14 can take and place food in the cooking cavity 11.

[0118] For example, the container cover 14 is square.

[0119] In the embodiments of the present disclosure, 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 opening and closing of the container cover 14. When the opened container cover 14 is moved away from the cooking cavity 11 at the opening of the cooking body 13, the second heater 3 is correspondingly moved away from the cooking cavity 11 at the opening of the cooking 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 moves back to the top of the cooking cavity 11 with the container cover 14, which is conducive to better heating of the food.

[0120] It can be understood that the position of the second heater 3 is not limited. For example, the second heater 3 can be installed on the cooking body 13.

The second cover 142 is connected to the side of the first cover 141 away from the cooking cavity 11, and the exhaust passage is at least across the first cover 141 and the second cover 142.

[0122] Exemplarily, the first cover 141 and the second cover 142 are square in shape.

[0123] In the embodiment of the present disclosure, the first cover 141 surrounds the cooking main body 13 to form the cooking cavity 11, and the second heater 3 is installed on the first cover 141, so that the second heater 3 located in the cooking cavity 11 is more convenient to install. The second cover 142 is connected to the side of the first cover 141 away from the cooking cavity 11, and the separation by the second cover 142 reduces the possibility of the user being scalded by directly contacting the relatively hot first cover 141. The exhaust passage is across the first cover 141 and the second cover 142, and the steam in the cooking cavity 11 can be discharged outward through the exhaust passage via the first cover 141 and the second cover 142.

[0124] It can be understood that the specific structure of the container cover 14 is not limited. Exemplarily, the second cover 142 can not be provided, and the second heater 3 is installed on the first cover 141. Exemplarily, the second heater 3 can be provided on the second cover 142.

[0126] Exemplarily, referring to FIGS. 1-5, the pressure limiting valve 4 is a hollow ball, and the pressure limiting valve 4 is pressed at the exhaust port 121 by gravity.

[0127] In the embodiment of the present disclosure, the pressure limiting valve 4 is installed at the exhaust port 121 of the first cover 141, and the pressure limiting valve 4 protruding from the side of the exhaust port 121 away from the cooking cavity 11 can be better constrained by the second cover 142 on the side of the first cover 141 away from the cooking cavity 11, which is conducive to maintaining the pressure limiting valve 4 at a position corresponding to the exhaust port 121 during repeated opening and closing of the valve to limit the pressure in the cooking cavity 11.

[0128] It can be understood that the installation position of the pressure limiting valve 4 is not limited. Exemplarily, the pressure limiting valve 4 can be installed to the second cover 142.

[0129] In an embodiment, referring to FIGS. 1-5, the first cover 141 is formed with a positioning boss 1411, the exhaust port 121 is formed in the positioning boss 1411, the second cover 142 is formed with a limiting sleeve 1421, the limiting sleeve 1421 is sleeved on the positioning boss 1411, the limiting sleeve 1421 and the positioning boss 1411 surround a limiting cavity 143 located above the positioning boss 1411, and the pressure limiting valve 4 is at least partially located in the limiting cavity 143.

[0130] Illustratively, referring to FIGS. 1-5, the positioning boss 1411 is cylindrical in shape, and the limiting sleeve 1421 is annular in shape.

[0131] Illustratively, the positioning boss 1411 is square in shape, and the limiting sleeve 1421 is square in shape.

[0132] Illustratively, referring to FIGS. 1-5, the limiting cavity 143 is part of the exhaust passage.

[0133] In the embodiments of the present disclosure, the second cover 142 is sleeved on the positioning boss 1411 through the limiting sleeve 1421, and the limiting sleeve 1421 and the positioning boss 1411 can better position the second cover 142 relative to the first cover 141. The pressure limiting valve 4 is at least partially located in the limiting cavity 143, and the limiting sleeve 1421 can also better constrain the pressure limiting valve 4, so that the pressure limiting valve 4 can still be constrained in the limiting cavity 143 during repeated valve opening and closing, thereby substantially maintaining the pressure limiting valve 4 at a position corresponding to the exhaust port 121 to limit the pressure of the cooking cavity 11.

[0134] It can be understood that the positions of the limiting sleeve 1421 and the positioning boss 1411 are not limited. Illustratively, the limiting sleeve 1421 can be located above the positioning boss 1411.

[0231] Third Embodiment

[0232] The embodiments of the present disclosure provide a cooking appliance. Referring to FIGS. 17-21, the cooking appliance includes a cooking body 13, a container cover 14, and a pressure limiting valve 4. The cooking body 13 has a cooking cavity 11, and the container cover 14 is arranged above the cooking cavity 11. The container cover 14 has an exhaust port 121 which communicates with the cooking cavity 11, and the pressure limiting valve 4 is arranged above the exhaust port 121. The pressure limiting valve 4 is a hollow structure.

[0233] The container cover 14 in the embodiments is equivalent to the cover body in the prior application with the application number “202422201917.X”.

[0234] For example, the container cover 14 is arranged above the cooking body 13, and the pressure limiting valve 4 is arranged above the exhaust port 121.

[0235] For example, 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 .

[0236] For example, 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 .

[0237] It can be understood that the shape of the exhaust port 121 is matched with the cross-sectional shape of the pressure limiting valve 4.

[0238] In the embodiments of the present disclosure, the pressure limiting valve 4 is arranged on 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 in the cooking cavity 11 from being discharged. During the cooking process, the steam in the cooking cavity 11 increases, and the pressure in the cooking cavity 11 increases. When the pressure in the cooking cavity 11 increases to a set value, the steam pushes the pressure limiting valve 4 with a force greater than the gravity, and the steam in the cooking cavity 11 can make the hollow pressure limiting valve 4 float up. The pressure limiting valve 4 is opened, and the exhaust port 121 can discharge the steam in the cooking cavity 11 to reduce the pressure in the cooking cavity 11. When the pressure in the cooking cavity 11 decreases to a set value, the pressure limiting valve 4 falls and is arranged on the exhaust port 121 again. The pressure limiting valve 4 is closed, and the exhaust port 121 can hardly discharge the steam. The hollow structure of the pressure limiting valve 4 has a small weight, and the opening pressure of the pressure limiting valve 4 is small. The hollow structure of the pressure limiting valve 4 can maintain a small pressure in the cooking cavity 11 during the cooking process. The weight and the volume of the pressure limiting valve 4 are small, and the size of the exhaust port 121 is large. The large-area exhaust port 121 can quickly discharge the gas in the cooking cavity 11 and reduce the pressure in the cooking cavity 11. When the cooking appliance is in a pressureless cooking state, the large-area exhaust port 121 can realize the same pressure inside and outside the cooking cavity 11.

[0239] In an embodiment, as shown in FIGS. 17-21, the exhaust port 121 is circular, and the pressure limiting valve 4 is a hollow spherical ball. 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.

[0240] In the embodiments of the present disclosure, under the action of the steam, the pressure limiting valve 4 can continuously rotate and jump on the exhaust port 121 to realize the opening and closing of the valve. The contact surface between the spherical pressure limiting valve 4 and the hole wall 918 of the exhaust port 121 is always circular. The spherical pressure limiting valve 4 can block the circular exhaust port 121 as much as possible.

[0241] It can be understood that the shape of the exhaust port 121 is not limited to a circle, and the pressure limiting valve 4 is not limited to a hollow spherical ball. For example, the pressure limiting valve 4 is a hollow ellipsoidal ball, and the shape of the exhaust port 121 is adapted to the cross-sectional shape of the pressure limiting valve 4.

[0242] For example, the pressure limiting valve 4 is a hollow square, and the shape of the exhaust port 121 is a square.

[0243] In an embodiment, as shown in FIGS. 17-21, the pressure limiting valve 4 includes a first shell 41 and a second shell 42 connected to each other. 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.

[0244] In the embodiments of the present disclosure, the pressure limiting valve 4 is divided into the first shell 41 and the second shell 42, and the first shell 41 and the second shell 42 are connected after being respectively manufactured, so that the pressure limiting valve 4 is manufactured into a hollow spherical ball.

[0245] It can be understood that the outer surface of the first shell 41 and the outer surface of the second shell 42 are not limited to be spherical caps. For example, the outer surface of the first shell 41 is a spherical cap, the first shell 41 has an opening, and the second shell 42 is a plug, which seals the opening of the first shell 41. In the manufacturing process of the hollow spherical ball, a spherical core is first manufactured, the core is placed in a spherical mold, and then the first shell 41 is obtained by pouring after closing the mold, the first shell 41 has an opening for removing the core after being cast, and then the opening of the first shell 41 is sealed by the second shell 42.

[0246] In an embodiment, referring to FIGS. 17-21, the pressure limiting valve 4 includes the first shell 41 and the second shell 42 connected to each other, and the weight of the first shell 41 is greater than the weight of the second shell 42.

[0247] It can be understood that the shape of the exhaust port 121 is matched with the cross-sectional shape of the first shell 41.

[0248] For example, the exhaust port 121 is circular, the shape of the first shell 41 is a semispherical ball, and the shape of the second shell 42 is not limited.

[0249] In the embodiments of the present disclosure, the weight of the first shell 41 is greater than the weight 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 deviates to the first shell 41. During the rotation and jumping of the pressure limiting valve 4, the first shell 41 with greater weight is located below under the action of gravity, and the first shell 41 is always in contact with the hole wall 918 of the exhaust port 121, so that the pressure limiting valve 4 can automatically correct the position in contact with the exhaust port 121, and avoid the situation that the joint between the first shell 41 and the second shell 42 may not be tightly sealed with the exhaust port 121.

[0250] It can be understood that the weight of the first shell 41 is not limited to be greater than the weight of the second shell 42. For example, the weight of the first shell 41 is equal to the weight of the second shell 42.

[0251] In an embodiment, referring to FIGS. 17-21, 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.

[0252] 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.

[0253] Exemplarily, when the first shell 41 and the second shell 42 are two hemispherical spherical caps, the outer diameter of the first shell 41 is equal to the outer diameter of the second shell 42, 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, and the distance is equal to the radius of the first shell 41 or the second shell 42.

[0254] In the embodiments of the present disclosure, the outer surfaces of the first shell 41 and the second shell 42 at the welding position can be relatively smooth, so as to reduce the unevenness of the outer surface of the pressure limiting valve 4 and reduce the gap between the pressure limiting valve 4 and the exhaust port 121.

[0255] It can be understood 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.

[0257] 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.

[0258] In the embodiments of the present disclosure, the first shell 41 and the second shell 42 can be made close to each other in shape, which is convenient for manufacturing the first shell 41 and the second shell 42, and the welding position of the first shell 41 and the second shell 42 is located at the maximum diameter of the spherical ball, which is also convenient for welding the first shell 41 and the second shell 42.

[0259] It can be understood that the outer surfaces of the first shell 41 and the second shell 42 are not limited to be located on the same spherical surface. Exemplarily, the outer surfaces of the first shell 41 and the second shell are not located on the same spherical surface.

[0260] In an embodiment, referring to FIGS. 17-21, the first shell 41 and the second shell 42 are made of the same material, and the difference between the wall thickness of the first shell 41 and the wall thickness of the second shell 42 is greater than or equal to 1 mm.

[0261] It should be explained that the unit “mm” is millimeter.

[0262] Exemplarily, the difference between the wall thickness of the first shell 41 and the wall thickness of the second shell 42 is 1 mm, 2 mm, 3 mm, or 4 mm.

[0263] In the embodiments of the present disclosure, the first shell 41 and the second shell 42 are made of the same material, so that the cost of manufacturing the first shell 41 and the second shell 42 can be reduced. The difference between the wall thickness of the first shell 41 and the wall thickness of the second shell 42 is greater than or equal to 1 mm, so that the first shell 41 and the second shell 42 have a sufficient weight difference, the pressure limiting valve 4 is obviously eccentric, and the pressure limiting valve 4 has a good correction effect.

[0264] It can be understood that the difference between the wall thickness of the first shell 41 and the wall thickness of the second shell 42 is not limited to greater than or equal to 1 mm. For example, the difference between the wall thickness of the first shell 41 and the wall thickness of the second shell 42 is less than 1 mm.

[0265] For example, the difference between the wall thickness of the first shell 41 and the wall thickness of the second shell 42 is 0.8 mm.

[0266] It can be understood that the materials of the first shell 41 and the second shell 42 are not limited to the same. For example, the materials of the first shell 41 and the second shell 42 are different, and the density of the material of the first shell 41 is greater than the density of the material of the second shell 42.

The diameter of the exhaust port 121 is less than or equal to 30 mm, so that the steam is not discharged too much, and the pressure in the cooking cavity 11 is not too small, which is beneficial to maintaining the pressure in the cooking cavity 11.

[0304] The up-down direction is the direction indicated by the arrow R2.

[0305] The cooking appliance provided by the embodiments of the present disclosure, please refer to FIG. 22-31, including a cooking container 1, a pressure-limiting valve 4 and a temperature measurer 940. The inside of the cooking container 1 has a working space 944, the working space 944 includes a cooking cavity 11 and sequentially communicates with a mounting cavity 919, an exhaust cavity 920 and an exhaust port 121. The pressure-limiting valve 4 is located in the working space 944, and the pressure-limiting valve 4 is at least partially located in the mounting cavity 919, and the pressure-limiting valve 4 is used for communicating or cutting off the mounting cavity 919 and the cooking cavity 11. The temperature measurer 940 is at least partially located in the exhaust cavity 920, the fluid in the exhaust cavity 920 flows to the exhaust port 121 through the temperature measurer 940, the arrangement direction of the pressure-limiting valve 4 and the temperature measurer 940 is a preset direction, and the exhaust cavity 920 extends from the pressure-limiting valve 4 to the temperature measurer 940 along the preset direction.

[0306] 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 is opened, and the steam in the cooking cavity 11 flows to the exhaust port 121 through the mounting cavity 919 and the exhaust cavity 920 through the pressure-limiting valve 4.

[0307] 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 is closed, and the steam in the cooking cavity 11 is substantially sealed in the cooking cavity 11 by the pressure-limiting valve 4.

[0308] Exemplarily, the pressure-limiting value of the pressure-limiting valve 4 is less than or equal to 5kPa.

[0309] Exemplarily, the pressure-limiting value of the pressure-limiting valve 4 is less than or equal to 5kPa, and the pressure-limiting value of the pressure-limiting valve 4 is greater than or equal to 1kPa.

[0310] Exemplarily, the diameter of the exhaust port 121 is greater than or equal to 10mm, or the sectional area of the exhaust port 121 is greater than or equal to 80mm 2 .

[0312] In the embodiment of the present disclosure, the working space 944 is located inside the cooking container 1, and the pressure limiting valve 4 is located in the working space 944. There is almost no installation gap between the pressure limiting valve 4 and the cooking container 1 for communication with the outside, thereby 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 is discharged through the pressure limiting valve 4, the installation cavity 919, the exhaust cavity 920 and the exhaust port 121 in sequence. Since the temperature measuring device 940 is located in the exhaust cavity 920, the steam discharged 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 conducive to increasing the amount of steam flowing through the temperature measuring device 940. In addition, 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 almost extends in a straight line, thereby reducing the flow resistance of the steam in the exhaust cavity 920, reducing the energy loss of the steam flow, reducing the contact time and exchange of the steam with the wall surface of the pipeline, and being conducive to inhibiting the formation of condensed water during the flow of the steam in the exhaust cavity 920, thereby increasing the amount of steam flowing to the temperature measuring device 940. Since the reduction of the amount of steam flowing to the temperature measuring device 940 due to leakage and the formation of condensed water is well inhibited, 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.
