Detailed implementation manners

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] In the various specific technical features described in the specific embodiments, they can be combined in any suitable manner without conflict. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination manners of the various specific technical features in the present application will not be described separately.

[0044] In the following description, the terms "first", "second", etc. only distinguish different objects and do not indicate any sameness or connection between the objects. It should be understood that the orientation descriptions such as "above", "below", "outside", and "inside" are all in the normal usage orientation, which can be the left - right direction in the normal usage state or not.

[0045] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or apparatus comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or apparatus comprising the element. "Plural" means greater than or equal to two.

[0046] In the related art, either the pressure - limiting valve part is located outside the cooking container, and there is a gap between the pressure - limiting valve and the cooking container, resulting in steam leakage from the pressure - limiting valve. Although the condensate is less, the steam leakage reduces the steam flowing to the temperature detector, causing inaccurate temperature measurement. Or the steam discharged from the pressure - limiting valve flows to the temperature detector through a bent exhaust cavity. The exhaust cavity is bent, resulting in large energy loss of steam flow. The steam can contact the pipe wall for a longer time, and heat exchange occurs between the relatively hot steam and the pipe wall, all of which will cause the steam to condense into condensate, resulting in a decrease in the amount of steam flowing from the pressure - limiting valve to the temperature detector.

[0047] The preset direction is the direction indicated by the arrow R1.

[0048] The up - down direction is the direction indicated by the arrow R2.

[0049] A cooking appliance provided by an embodiment of the present application, please refer to Figures 1 to 10 , which includes a cooking container 1, a pressure - limiting valve 2, and a temperature detector 3. The interior of the cooking container 1 has a working space 11, and the working space 11 includes a cooking cavity 111 and an installation cavity 112, an exhaust cavity 113, and an exhaust port 114 that are connected in sequence. The pressure - limiting valve 2 is located in the working space 11, and at least part of the pressure - limiting valve 2 is located in the installation cavity 112. The pressure - limiting valve 2 is used to connect or cut off the installation cavity 112 and the cooking cavity 111. The temperature detector 3 is at least partially located in the exhaust cavity 113. The fluid in the exhaust cavity 113 flows through the temperature detector 3 to the exhaust port 114. The arrangement direction of the pressure - limiting valve 2 and the temperature detector 3 is the preset direction, and the exhaust cavity 113 extends from the pressure - limiting valve 2 to the temperature detector 3 along the preset direction.

[0050] When the pressure in the cooking chamber 111 is greater than or equal to the pressure limit value of the pressure limiting valve 2, the pressure limiting valve 2 opens, and the steam in the cooking chamber 111 flows through the pressure limiting valve 2, through the installation chamber 112 and the exhaust chamber 113, towards the exhaust port 114.

[0051] When the pressure in the cooking chamber 111 is less than the pressure limit value of the pressure limiting valve 2, the pressure limiting valve 2 closes, and the steam in the cooking chamber 111 is basically sealed in the cooking chamber 111 by the pressure limiting valve 2.

[0052] Exemplarily, the pressure limit value of the pressure limiting valve 2 is less than or equal to 5 kPa.

[0053] Exemplarily, the pressure limit value of the pressure limiting valve 2 is less than or equal to 5 kPa, and the pressure limit value of the pressure limiting valve 2 is greater than or equal to 1 kPa.

[0054] In the embodiment of the present application, the working space 11 is located inside the cooking container 1, the pressure limiting valve 2 is located in the working space 11, and there is almost no installation gap communicating with the outside between the pressure limiting valve 2 and the cooking container 1, reducing steam leakage. When the pressure in the cooking chamber 111 is greater than the pressure limit value of the pressure limiting valve 2, the steam in the cooking chamber 111 passes through the pressure limiting valve 2 and is discharged through the installation chamber 112, the exhaust chamber 113, and the exhaust port 114 in sequence. Since the temperature measuring device 3 is in the exhaust chamber 113, the steam discharged through the pressure limiting valve 2 towards the exhaust port 114 can flow through the temperature measuring device 3 in the exhaust chamber 113 as much as possible, which is beneficial to increasing the amount of steam flowing through the temperature measuring device 3. Furthermore, the exhaust chamber 113 extends from the pressure limiting valve 2 towards the temperature measuring device 3 along the preset direction, and the exhaust chamber 113 extends almost linearly, reducing the flow resistance of the steam in the exhaust chamber 113, 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 chamber 113, and increasing the amount of steam flowing towards the temperature measuring device 3. Since the situation where the amount of steam flowing towards the temperature measuring device 3 is reduced due to leakage and the formation of condensed water is better suppressed, the amount of steam flowing towards the temperature measuring device 3 is increased, so that the steam temperature measured by the temperature measuring device 3 is more accurate.

[0055] In one embodiment, please refer to Figures 1 to 10 , the temperature measuring device 3 has a temperature sensing part 31 for temperature measurement, and the span of the exhaust chamber 113 in the vertical direction at the position corresponding to the temperature measuring device 3 is a preset distance; the temperature sensing part 31 is located at the bottom of the exhaust chamber 113 and within the interval of 2 / 3 of the preset distance upward from the bottom of the exhaust chamber 113.

The interval corresponding to the dimension D1 shown in the figure, that is, the bottom of the exhaust cavity 113 and the interval that is half of the preset distance upward from the bottom of the exhaust cavity 113.

[0059] Exemplarily, please refer to Figures 1 to 10 , the dimension D2 shown in the figure is the preset distance.

So that the container lid 13 can be detached from the cooking main body 12 for opening more conveniently.

[0066] Exemplarily, the temperature detector 3 can be located on the container lid 13.

The valve body 23 is located in the space surrounded by the valve seat 21 and the valve cover 22, and the valve body 23 is used to communicate or cut off the installation cavity 112 and the cooking cavity 111.

[0068] Exemplarily, please refer to Figures 1 to 10 , the valve seat 21 and the valve cover 22 are detachably connected.

[0069] Exemplarily, please refer to Figures 1 to 10 , the valve seat 21 and the valve cover 22 are threadedly connected so that the container cover 13 is partially clamped between the valve seat 21 and the valve cover 22.

[0070] Exemplarily, the steam in the cooking cavity 111 pushes the valve body 23 to move.

[0071] Exemplarily, the shape of the valve body 23 can be flat.

[0072] Exemplarily, the shape of the valve body 23 can be spherical.

[0073] Exemplarily, the valve body 23 is a hollow sphere.

[0074] In the embodiment of the present application, the container cover 13 is partially clamped between the valve seat 21 and the valve cover 22 through the mutually connected valve seat 21 and valve cover 22, so that the pressure limiting valve 2 is relatively firmly installed on the container cover 13. The opening and closing of the pressure limiting valve 2 are realized by the movement of the valve body 23 in the space surrounded by the valve seat 21 and the valve cover 22.

[0076] In the embodiment of the present application, by moving the valve body 23 in the second cavity 24, the first cavity 211 and the second cavity 24 are communicated or cut off, thereby realizing the opening and closing of the pressure limiting valve 2.

[0077] Exemplarily, there may be no second cavity 24, the valve cover 22 partially extends into the cooking cavity 111, the valve seat 21 is sleeved outside the valve cover 22, and the connection port between the first cavity 211 and the cooking cavity 111 is opened or closed by the valve body 23.

[0078] In one embodiment, please refer to Figures 1 to 10 , an opening on a side of the first chamber 211 facing the second chamber 24 is a transition air port 2111.

The valve body 23 is configured to move into contact with the sealing end face 212 to close the transition air port 2111, and the valve body 23 is configured to move out of contact with the sealing end face 212 to open the transition air port 2111.

[0079] In the embodiment of the present application, since the valve seat 21 is located on a side of the sealing end face 212 away from the second chamber 24 along the arrangement direction of the first chamber 211 and the second chamber 24, and the valve body 23 is located on a side of the sealing end face 212 away from the valve seat 21, the valve body 23 is entirely located at one end of the valve seat 21 away from the cooking chamber 111. The valve body 23 hardly laterally wraps the side of the valve seat 21. The valve body 23 can achieve the opening and closing of the pressure limiting valve 2 with a relatively small thickness dimension along the arrangement direction of the first chamber 211 and the second chamber 24, reducing space occupation and improving space utilization rate.

[0080] Exemplarily, the valve body 23 can be sleeved on the valve seat 21.

[0081] In one embodiment, please refer to Figures 1 to 10 , the valve seat 21 is formed with air inlet holes 213 respectively communicating with the first chamber 211 and the cooking chamber 111. At least one of the air inlet holes 213 is located on a side wall of the valve seat 21. The axial direction of the air inlet hole 213 located on the side wall of the valve seat 21 and the arrangement direction of the first chamber 211 and the second chamber 24 are arranged crosswise.

[0082] Exemplarily, at least one air inlet hole 213 is located on the bottom wall of the valve seat 21.

[0083] Exemplarily, the number of the air inlet holes 213 located on the side wall of the valve seat 21 can be at least two.

[0084] In the embodiment of the present application, since the air inlet holes 213 on the side wall of the valve seat 21 are not in the same direction as the direction of the upward impact of the boiling liquid in the cooking chamber 111, the air inlet holes 213 on the side wall of the valve seat 21 can prevent the boiling liquid in the cooking chamber 111 from directly flushing into the first chamber 211, which is beneficial to preventing the liquid in the cooking chamber 111 from overflowing.

[0085] Exemplarily, the first chamber 211 can penetrate downward through the valve seat 21 to communicate with the cooking chamber 111, and the valve seat 21 is not provided with a bottom wall.

[0086] In one embodiment, please refer to Figures 1 to 10 , the valve cover 22 is formed with air outlet holes 221 that communicate with the second chamber 24 and the exhaust chamber 113 respectively. At least one of the air outlet holes 221 is located on the side wall of the valve cover 22. The axial direction of the air outlet hole 221 located on the side wall of the valve cover 22 and the arrangement direction of the first chamber 211 and the second chamber 24 are arranged crosswise, and the arrangement direction of the first chamber 211 and the second chamber 24 is arranged crosswise with the preset direction.

[0087] Exemplarily, at least one air outlet hole 221 is located on the top wall of the valve cover 22.

[0088] Exemplarily, the number of the air outlet holes 221 located on the side wall of the valve cover 22 can be at least two.

[0089] Exemplarily, the axial direction of the air outlet hole 221 located on the side wall of the valve cover 22 is parallel to the preset direction.

[0090] In the embodiment of the present application, since the air outlet holes 221 on the side wall of the valve cover 22 are not in the same direction as the direction in which the liquid in the cooking chamber 111 boils and impacts upward, the liquid in the first chamber 211 and the second chamber 24 can be prevented from rushing out through the air outlet holes 221 on the side wall of the valve cover 22, which is beneficial to preventing the liquid in the cooking chamber 111 from overflowing. In addition, since the axial direction of the air outlet holes 221 located on the side wall of the valve cover 22 and the arrangement direction of the first chamber 211 and the second chamber 24 are arranged crosswise, and the arrangement direction of the first chamber 211 and the second chamber 24 is arranged crosswise with the preset direction, the direction of the air outlet holes 221 on the side wall of the valve cover 22 is close to the preset direction, so that the steam discharged from the air outlet holes 221 on the side wall of the valve cover 22 can flow smoothly to the exhaust port 114 through the exhaust chamber 113.

[0091] In one embodiment, please refer to Figures 1 to 10, the cooking main body 12 includes a main body 121, a housing cover 122, and a mounting base 123.

The mounting base 123 is connected to the housing cover 122. The mounting base 123 at least partially protrudes from the housing cover 122. The mounting base 123 and the container cover 13 enclose the exhaust cavity 113. The exhaust port 114 is formed in the mounting base 123. The reinforcing boss 1221 is located between the mounting base 123 and the pressure limiting valve 2 along the preset direction. The temperature detector 3 is mounted on the mounting base 123.

[0092] In the embodiment of the present application, the position where the housing cover 122 is connected to the mounting base 123 is strengthened by the reinforcing boss 1221, reducing the possibility of the housing cover 122 cracking.

[0093] Exemplarily, the housing cover 122 and the container cover 13 can enclose the exhaust cavity 113, and the temperature detector 3 can be mounted on the housing cover 122.

[0094] Exemplarily, the main body 121 and the container cover 13 can enclose the exhaust cavity 113, and the temperature detector 3 can be mounted on the main body 121.

[0098] Exemplarily, please refer to Figures 1 to 10 , the locking mechanism 4 is a slider movably mounted on the cooking main body 12. When the container cover 13 is placed on the cooking main body 12, the slider is moved so that the slider is partially located above the container cover 13 to lock the container cover 13.

[0099] Exemplarily, please refer to Figures 1 to 10, the shape of the container lid 13 is square.

[0100] In an embodiment of the present application, the container lid 13 is locked to the cooking main body 12 through a locking mechanism 4, so that the cooking cavity 111 formed by the container lid 13 and the cooking main body 12 can withstand cooking under a certain pressure environment, and the container lid 13 will not be pushed open by the pressure in the cooking cavity 111.
