[0044] Example 1

[0045] This embodiment provides a cooking device that utilizes hot steam to cook food while increasing the initial heating rate and enhancing the cooking experience. The cooking device can be, but is not limited to, an electric steam oven, a steam oven, or a microwave-steam-grill combination appliance with steam cooking capabilities.

[0046] like Figures 1 to 3 As shown, the cooking equipment includes a body, a steam cooking module, and a controller. The body includes an inner pot assembly 7, a base located at the bottom of the inner pot assembly 7, and an outer shell surrounding the inner pot assembly 7. The inner pot assembly 7 has a cooking cavity with an open front side and a steam exhaust port 7211 communicating with the cooking cavity. The steam cooking module supplies hot steam to the cooking cavity to cook the food inside. The controller is installed in the body and communicates with the steam cooking module, controlling the operation of the steam cooking module.

[0047] To facilitate the smooth discharge of steam from the cooking cavity, this embodiment of the cooking equipment further includes a steam discharge device. The steam discharge device includes an exhaust connector assembly 1 and an exhaust pipe 2. The exhaust connector assembly 1 includes a housing 11, a flow regulating component 12, and an elastic component 13. The housing 11 has an exhaust chamber 115 and a steam inlet 110 and an exhaust port 116 communicating with the exhaust chamber 115. The flow regulating component 12 includes a ventilation regulating member 121, which is slidably disposed within the housing 11. The elastic component 13 is disposed in the exhaust chamber 115 and applies an elastic force towards the steam inlet 110 to the ventilation regulating member 121. The ventilation regulating member 121 can move away from the steam inlet 110 when the intake pressure of the steam inlet 110 is greater than a preset pressure, thereby increasing the actual conduction area between the exhaust port 116 and the steam inlet 110. The intake end of the exhaust pipe 2 communicates with the exhaust port 116, and the steam inlet 110 communicates with the steam exhaust port 7211.

[0048] The steam emission device provided in this embodiment, by setting an exhaust connector assembly 1 that can adjust the actual conduction area between the exhaust port 116 and the steam inlet 110, ensures that when the gas pressure in the cooking chamber is low, the actual conduction area between the exhaust port 116 and the steam inlet 110 is small, thereby reducing steam leakage from the cooking chamber and facilitating rapid heating of the cooking chamber. When the pressure in the cooking chamber increases, the intake pressure of the steam inlet 110 increases, and the ventilation adjustment assembly moves away from the steam inlet 110 to increase the actual conduction area between the exhaust port 116 and the steam inlet 110, thereby increasing the exhaust flow rate, ensuring smooth steam emission and pressure relief, and ensuring the reliability of the steam emission device.

[0049] It is worth mentioning that the actual conduction area between the steam inlet 110 and the exhaust port 116 specifically refers to the minimum air passage area on the flow path of the steam flowing from the steam inlet 110 to the exhaust port 116.

[0050] The inner container assembly 7 includes an inner container body 71 and an air duct support 72 arranged outside the inner container body 71, and a steam exhaust device is mounted on the side of the air duct support 72 away from the inner container body 71. A steam outlet 711 is formed on the container wall of the inner container body 71, and a steam exhaust port 7211 is formed on the air duct support 72. The steam outlet 711 and the steam exhaust port 7211 are in communication. The shell 11 is mounted on the air duct support 72 and the steam inlet 110 and the steam exhaust port 7211 are in direct communication. That is, when the air adjustment component 121 is in the first position, the air duct support 72 blocks the air hole 1211.

[0051] Specifically, the air duct support 72 includes an inner air duct plate 721 and an outer air duct plate 722 connected detachably. The inner air duct plate 721 is located between the inner container body 71 and the outer air duct plate 722, and the inner air duct plate 721 and the outer air duct plate 722 jointly form a partition cavity 723. The steam exhaust port 7211 is formed on the inner air duct plate 721, and the first avoiding hole 7221 is formed on the outer air duct plate 722.

[0052] The air duct support 72 has the partition cavity 723. The steam exhaust port 7211 is formed on the side cavity wall of the partition cavity 723 facing the inner container body 71, and the first avoiding hole 7221 is formed on the side cavity wall of the partition cavity 723 away from the inner container body 71. The exhaust connector assembly 1 is located in the first avoiding hole 7221, so that part of the exhaust connector assembly 1 is accommodated in the partition cavity 723 to facilitate the cooperation with the steam exhaust port 7211, and the other part of the exhaust connector assembly 1 is located outside the air duct support 72 to facilitate the cooperation of the exhaust connector assembly 1 with the exhaust pipe 2. At the same time, by arranging the partition cavity 723, the conduction of the heat of the inner container to the heat sink 3 and the exhaust pipe 2 can be reduced, and the condensation effect of the exhaust pipe 2 on the steam can be improved.

[0053] In the embodiment, the exhaust pipe 2 includes an exhaust main pipe 21 and an adapter pipe 22. The two ends of the adapter pipe 22 are detachably connected with the exhaust main pipe 21 and the shell 11, respectively. Therefore, the exhaust main pipe 21 can be arranged in a general manner, and the structure of the adapter pipe 22 can be selected according to the relative arrangement of the exhaust main pipe 21 and the exhaust port 116. The processing cost of the exhaust pipe 2 is reduced, and the relative position requirements of the exhaust pipe 2 and the exhaust connector assembly 1 are reduced. The adapter pipe 22 is preferably a flexible pipe.

[0054] In the embodiment, the steam exhaust device comprises at least two exhaust pipes 2, the number of exhaust ports 116 is the same as the number of exhaust pipes 2, each exhaust pipe 2 is connected at the corresponding exhaust port 116, thereby shortening the outer diameter and length requirements of the single exhaust pipe 2 while ensuring the smoothness and exhaust effect of the exhaust. The number of exhaust ports 116 is preferably 2, 3 or 4. The exhaust ports 116 are arranged in a circumferential direction of the exhaust cavity 115 to avoid interference between the exhaust pipes 2.

[0055] In the embodiment, the steam exhaust device further comprises a heat sink 3 and a heat sink fan 4, the heat sink 3 comprises a plurality of heat sink fins arranged transversely and in parallel, the exhaust pipe 2 comprises a plurality of condensation sections connected by bending sections from top to bottom, and each condensation section passes through a plurality of heat sink fins. The heat sink fan 4 guides external cooling airflow to the heat sink 3 to cool the exhaust pipe 2, and the cooling airflow carries away heat from the heat sink 3 to ensure the cooling effect of the heat sink 3 on the exhaust pipe 2, so that the hot steam flowing in the exhaust pipe 2 can be condensed and cooled, reducing the steam content and temperature of the steam discharged from the exhaust pipe 2, and improving the use experience of the steam exhaust device and the cooking equipment. Specifically, the exhaust main pipe 21 comprises condensation sections and bending sections.

[0056] Further, the second avoiding hole is formed in the side cavity wall of the separation cavity 723 away from the inner container main body 71, and the bending pipe section of the exhaust pipe 2 towards the air duct support 72 is located in the second avoiding hole, thereby improving the compactness of the structure and reducing the floor space of the steam exhaust device.

[0057] The steam exhaust device further comprises a water collecting box 5, the lower end of the condensation pipe is connected to the water collecting box 5, so that the condensed water formed in the exhaust pipe 2 is collected into the water collecting box 5. Further, the bottom of the water collecting box 5 is provided with a drain port, and the drain pipe 6 is connected at the drain port, and the drain control valve is arranged on the drain pipe 6, thereby facilitating the discharge of the condensed water without disassembling the water collecting box 5. The upper part of the water collecting box 5 is provided with an overflow port, so that the gas entering the water collecting box 5 can overflow outward through the overflow port, avoiding excessive gas pressure in the water collecting box 5.

[0058] As Figures 3 to 5As shown, in the present embodiment, the steam inlet 110 and the exhaust port 116 are arranged at intervals in the sliding direction of the flow regulating member 12, the vent regulating component 121 is in sliding sealing engagement with the cavity wall of the exhaust cavity 115, and a plurality of vent holes 1211 are formed in the vent regulating component 121. The vent regulating component 121 has a first position between the steam inlet 110 and the exhaust port 116 and a second position away from the steam inlet 110 relative to the first position, and when the vent regulating component 121 is in the first position, at least part of the vent holes 1211 can be blocked by the opening plane of the steam inlet 110 or the opening plane of the steam discharge port 7211.

[0059] That is, since the steam entering the steam inlet 110 flows to the exhaust port 116 through the vent holes 1211, the total actual conduction area of the holes is adjusted, that is, the actual conduction area of the steam inlet 110 and the exhaust port 116 is adjusted, and the structure of the flow regulating member 12 is simple and easy to control the sliding direction of the flow regulating member 12.

[0060] The distances between all the exhaust ports 116 and the steam inlet 110 are equal, so that the hot steam entering the exhaust cavity 115 from the steam inlet 110 can be simultaneously introduced into the plurality of exhaust ports 116, and the vent regulating component 121 can simultaneously regulate the exhaust flow of the plurality of exhaust ports 116.

[0061] In another embodiment, the exhaust port 116 is a long slot, and the extension direction of the exhaust port 116 is consistent with the sliding direction of the flow regulating member 12, the vent regulating component 121 can block at least part of the exhaust port 116, and the sliding of the vent regulating component 121 in the direction away from the steam inlet 110 can increase the opening degree of the exhaust port 116, thereby increasing the actual conduction area of the exhaust port 116 and the steam inlet 110, and the sliding of the vent regulating component 121 in the direction toward the steam inlet 110 can increase the blocking of the exhaust port 116, thereby reducing the opening degree of the exhaust port 116, that is, reducing the actual conduction area of the exhaust port 116 and the steam inlet 110.

[0062] When the vent regulating component 121 is in the second position, all the vent holes 1211 are completely opened. That is, when the vent regulating component 121 is in the first position, the steam inlet 110 and the exhaust port 116 have the minimum actual conduction area, and the steam flow allowed to be introduced into the exhaust joint assembly 1 is the minimum exhaust flow; when the vent regulating component 121 is in the second position, the steam inlet 110 and the exhaust port 116 have the maximum actual conduction area, and the maximum steam flow allowed to be introduced into the exhaust joint assembly 1 is the maximum exhaust flow.

[0063] In the embodiment, when the ventilation adjusting component 121 is in the first position, all the ventilation holes 1211 are blocked by the opening plane of the steam discharge port 7211 or the steam inlet 110, that is, the actual conduction area of the steam inlet 110 and the exhaust port 116 is zero at this time, and the minimum exhaust flow is zero, which can effectively realize the rapid heating of the cooking cavity. In other embodiments, the minimum exhaust flow can also be non-zero.

[0064] In the embodiment, one end of the exhaust cavity 115 is open and the other end is closed, the opening of the exhaust cavity 115 forms the steam inlet 110, and the side cavity wall of the exhaust cavity 115 is provided with the exhaust port 116. That is, when the ventilation adjusting component 121 is in the first position, the inner container assembly 7 blocks at least part of the ventilation holes 1211. Such a configuration can simplify the structure of the shell 11, and at the same time, the open end and the closed end of the shell 11 are beneficial to the installation of the flow adjusting component 12 and the elastic component 13 in the exhaust cavity 115, and simplify the structure of the exhaust connector assembly 1.

[0065] In another embodiment, one end of the exhaust cavity 115 is open and the other end is closed, and the closed end of the exhaust cavity 115 is provided with the steam inlet 110. The flow adjusting component 12 is provided with a sealing part, which is located on the side of the exhaust port 116 away from the steam inlet 110, and the sealing part is in sealing sliding fit with the cavity wall of the exhaust cavity 115.

[0066] In another embodiment, the exhaust cavity 115 can also be provided with two closed ends, and one end of the exhaust cavity 115 is provided with the steam inlet 110. When the ventilation adjusting component 121 is in the first position, the cavity wall of the exhaust cavity 115 blocks the ventilation holes 1211.

[0067] When the ventilation adjusting component 121 is in the first position, the elastic component 13 applies an elastic force to the ventilation adjusting component 121 towards the steam inlet 110, so that the ventilation adjusting component 121 can stably and closely fit the opening plane of the steam discharge port 7211, ensuring the sealing; at the same time, by setting the elastic force of the ventilation adjusting component 121 in the first position, the preset pressure can be set, thereby avoiding the problem of excessive pressure in the inner container caused by the steam inlet 110 being opened only by a large steam pressure, and also avoiding the problem of the flow adjusting effect being not obvious caused by the steam inlet 110 being opened only by a small steam pressure. Specifically, the two ends of the elastic component 13 respectively abut against the ventilation adjusting component 121 and the cavity bottom of the exhaust cavity 115.

[0068] In the embodiment, when the ventilation adjusting component 121 is between the first position and the second position, the actual ventilation area of the ventilation hole 1211 is equal to the actual ventilation area of the ventilation adjusting component 121 in the second position, that is, when the ventilation adjusting component 121 is away from the first position, the ventilation hole 1211 is completely opened. This kind of arrangement can simplify the structure of the flow adjusting piece 12, and at the same time, simplify the cooperation structure of the exhaust joint assembly 1 and the inner container assembly 7, thereby reducing the cost of the cooking device.

[0069] Further, the ventilation adjusting component 121 is in a plate structure, and the plate structure is perpendicular to the sliding direction of the ventilation adjusting component 121, thereby facilitating the sliding of the ventilation adjusting component 121 in the exhaust cavity 115, and facilitating the fit of the ventilation adjusting component 121 and the inner container assembly 7.

[0070] In the embodiment, the ventilation adjusting component 121 is preferably in a circular plate structure, and the cross section of the exhaust cavity 115 is circular. In other embodiments, the shape of the ventilation adjusting component can also be rectangular or other shapes, as long as the shape of the ventilation adjusting component is the same as the cross-sectional shape of the exhaust cavity 115. The ventilation adjusting component is preferably made of elastic materials such as rubber or silicone, so as to ensure the sealing between the ventilation adjusting component 121 and the cavity wall of the exhaust cavity 115.

[0071] In the embodiment, the ventilation hole 1211 is arranged in multiple along the circumferential direction of the ventilation adjusting component 121, thereby being able to reduce the size of the single ventilation hole 1211 while ensuring the smoothness of the exhaust, so as to ensure the structural strength and rigidity of the flow adjusting piece 12. Further, the orthogonal projection of all the ventilation holes 1211 on the opening plane of the steam discharge port 7211 is arranged to be offset from the steam discharge port 7211, so that when the ventilation adjusting component 121 is in the first position, the inner container assembly 7 can block the steam inlet 110.

[0072] In order to improve the sliding stability of the ventilation adjusting component 121, a guide rod 122 is connected to the ventilation adjusting component 121, and a guide hole is formed in the cavity wall of the exhaust cavity 115 away from the steam inlet 110. The guide rod 122 is slidably arranged in the guide hole, so as to provide a guide for the sliding of the flow adjusting piece 12, thereby avoiding the problem of sliding jam caused by the deviation of the flow adjusting piece 12 during the sliding process.

[0073] In the embodiment, the shell 11 has a cavity 117 arranged side by side and separated from the exhaust cavity 115, the cavity 117 is located on the side of the exhaust cavity 115 away from the steam inlet 110, the guide hole communicates the cavity 117 and the exhaust cavity 115, and the end of the guide rod 122 away from the ventilation adjusting component 121 is located in the cavity 117 to avoid steam leakage outside the shell 11 through the guide hole; at the same time, the flow adjusting piece 12 can be always located inside the shell 11 to improve the appearance of the exhaust joint assembly 1. In other embodiments, the guide rod 122 can also be in sliding sealing cooperation with the guide hole, and the end of the guide rod 122 away from the ventilation adjusting component 121 can be located outside the shell 11.

[0074] Further, the end of the guide rod 122 away from the ventilation adjusting component 121 is provided with a limiting component 123, the limiting component 123 is limited to pass through the guide hole, thereby preventing the ventilation adjusting component 121 from being pulled out of the exhaust cavity 115, and ensuring the setting stability of the flow adjusting piece 12. The limiting component 123 is preferably detachably connected with the guide rod 122 to facilitate the mounting and dismounting of the flow adjusting piece 12 on the shell 11. For example, the end of the guide rod 122 away from the ventilation adjusting component 121 is provided with external threads, and the limiting component 123 is a nut structure screwed on the guide rod 122.

[0075] In the embodiment, the elastic piece 13 is sleeved on the guide rod 122 and the two ends thereof abut against the ventilation adjusting component 121 and the cavity wall of the exhaust cavity 115 away from the steam inlet 110, respectively, to improve the installation convenience of the elastic piece 13.

[0076] When the exhaust joint assembly 1 is not mounted on the inner container assembly 7, the limiting component 123 abuts against the separating component 113, and the head part of the flow adjusting piece 12 protrudes out of the steam outlet 711, thereby when the exhaust joint assembly 1 is mounted on the inner container assembly 7, the inner container assembly 7 extrudes the ventilation adjusting component 121 to slide towards the inside of the exhaust cavity 115, so that the ventilation adjusting component 121 can abut against the inner container assembly 7 to ensure the sealing effect of the inner container assembly 7 on the steam inlet 110.

[0077] In the embodiment, the inner container assembly 7 has a mounting surface for mounting the exhaust joint assembly 1, the mounting surface is partially recessed in the direction towards the cooking cavity to form a recessed part 7212, the bottom of the recessed part 7212 is provided with a steam discharge port 7211, and the orthographic projection of the exhaust cavity 115 on the mounting surface is located to cover the orthographic projection of the recessed part 7212 on the mounting surface. The provision of the recessed part 7212 can make the ventilation adjusting component 121 and the recessed part 7212 form an air inlet cavity when the ventilation adjusting component 121 is in the first position, and the steam enters the air inlet cavity and then acts on the ventilation adjusting component 121, thereby facilitating the control of the steam pressure acting on the ventilation adjusting component 121. Specifically, the recessed part 7212 is arranged on an inner air duct plate 721.

[0078] To improve the convenience of connecting the exhaust joint assembly 1 and the exhaust pipe 2, in the embodiment, the shell 11 comprises an exhaust cylinder part 111 and a joint pipe part 112 protrudingly arranged on the outer wall of the exhaust cylinder part 111, the inner cavity of the exhaust cylinder part 111 forms an exhaust cavity 115, the port of the joint pipe part 112 forms an exhaust port 116, and the joint pipe part 112 and the exhaust pipe 2 are sealingly and fitingly matched. In other embodiments, the exhaust pipe 2 can also be directly sealingly inserted into the exhaust cavity 115.

[0079] The open end of the exhaust cylinder part 111 extends outwardly with a flange part 114, the flange part 114 is attached to and fastened with the air duct support 72, so as to improve the installation convenience and stability of the shell 11 on the inner container assembly 7.

[0080] Other structures of the cooking device can be arranged according to the prior art, which is not the focus of the present application, and will not be described here.

[0081] Embodiment Two

[0082] The embodiment provides a steam exhaust device and a cooking device comprising the steam exhaust device, and the steam exhaust device provided by the embodiment is basically the same as the steam exhaust device in Embodiment One, only the difference is in the partial arrangement, and the same content as Embodiment One will not be described here.

[0083] As shown in Figure 6 and Figure 7 In the embodiment, when the air adjusting part 121 slides from the first position to the second position, the total actual air area of the air hole 1211 gradually increases, so that the greater the steam pressure acting on the air adjusting part 121, the greater the total actual air area of the air hole 1211, and the higher the steam flow allowed to enter.

[0084] Specifically, the shell 11 has an air inlet sleeve part 119 arranged around the steam inlet 110, the air inlet sleeve part 119 is located in the exhaust cavity 115, the air adjusting part 121 is slidingly sleeved on the outer side of the air inlet sleeve part 119 and closes the end opposite to the air inlet sleeve part 119, the side wall of the air inlet sleeve part 119 is provided with a plurality of air holes 1211, the air holes 1211 are communicated with the exhaust cavity 115, and the sliding of the air adjusting part 121 relative to the air inlet sleeve part 119 adjusts the area of the air holes 1211 blocked by the air inlet sleeve part 119. The elastic member is arranged between the cavity bottom of the exhaust cavity 115 and the air adjusting part 121.

[0085] The cooperation of the adjusting component and the shell 11 is arranged such that the closer the air passage adjusting component 121 is to the steam inlet 110, the more air passage holes 1211 are blocked, and the farther the air passage adjusting component 121 is from the steam inlet 110, the smaller the area of the air passage holes 1211 that are blocked; and the adjustment is realized through the sliding cooperation of the air inlet sleeve part 119 and the air passage adjusting part, and the adjustment reliability is high.

[0086] In the embodiment, the air passage holes 1211 are arranged in multiple groups along the extension direction of the air passage adjusting component 121, and each group includes multiple air passage holes 1211 arranged along the circumference of the air passage adjusting component 121. The arrangement of the air passage holes 1211 can reduce the size of a single air passage hole 1211, thereby ensuring the overall structural strength and rigidity of the flow adjusting piece 12.

[0087] In other embodiments, the air passage holes 1211 are long strip holes extending along the sliding direction of the air passage adjusting component 121.

[0088] In the embodiment, when there is no steam entering the steam inlet 110, the air passage adjusting part is in the first position, and all the air passage holes 1211 are blocked by the air inlet sleeve part 119. When the air passage adjusting part abuts against the cavity bottom of the exhaust cavity 115, the air passage adjusting part is in the second position, and all the air passage holes 1211 are open. That is, the air passage adjusting part slides between the first position and the second position.

[0089] To reduce the processing difficulty of the shell 11, the shell 11 includes an exhaust cylinder part 111 and an end cover part 118, one end of the exhaust cylinder part 111 is open and the other end is closed, and the end cover part 118 is detachably arranged at the opening of the exhaust cylinder part 111 and cooperates with the exhaust cylinder part 111 to form the exhaust cavity 115. The steam inlet 110 is arranged on the end cover part 118, and the air inlet sleeve part 119 is arranged on the end cover part 118 and protrudes towards the inside of the exhaust cylinder part 111, and the air inlet sleeve part 119 is arranged away from the cavity bottom of the exhaust cavity 115.

[0090] The remaining structure of the exhaust connector assembly 1 can be arranged according to the first embodiment, and the present embodiment will not be described again.

[0091] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application.
