[0009] The pressure relief component further includes a fixing part, the fixing part is arranged on the outer end of the exhaust duct and is connected to the baffle, and the baffle is adapted to rotate relative to the fixing part.

[0010] The fixing part includes: a connecting part, which protrudes from the outer end of the exhaust duct;

[0012] The connecting part is arranged in a plate shape, and the thickness direction of the connecting part is perpendicular to the extending direction of the baffle.

[0013] The baffle includes: a first plate member, which is sheet-shaped and has a shadow area projected on the outer end of the exhaust duct larger than the opening area of the pressure relief port, and is adapted to abut against the pressure relief port in a closed state and completely cover the pressure relief port;

[0021] An annular enclosing plate is provided on the circumferential side of the base pipe.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. The present invention provides a cooking device, including: a cooking cavity, with a first exhaust port provided on the cooking cavity; an exhaust duct, the inner end of which is connected to the position of the first exhaust port and is adapted to discharge the steam in the cooking cavity to the outside; a pressure relief component, including a baffle, the baffle is arranged on the outer end of the exhaust duct and is adapted to block the pressure relief port of the exhaust duct, and the baffle has a closed state of abutting against the pressure relief port and an exhaust state of leaving the pressure relief port under the push of steam.

[0024] By arranging a baffle at the outer end of the exhaust duct to block the exhaust duct, heat leakage in the cooking cavity is avoided, the thermal efficiency of the device is improved, and the temperature uniformity of the whole cooking device is ensured. Also, it is avoided that the temperature point below the pressure relief port is too low, resulting in inconsistent cooking degrees of food and affecting user consumption. In addition, the opening and closing of the pressure relief port are controlled by the baffle, with a simple structure and high stability.

[0025] 2. In the cooking device provided by the present invention, the power source is a cooling fan.

[0026] When the steam reaches a certain pressure, the steam will drive the baffle to tilt upward. At this time, the acting force generated by the power source and the steam together will lift the baffle, thereby ensuring the normal progress of pressure relief. The setting of the power source can apply an acting force to the second plate member, causing the first plate member connected to the second plate member to leave the pressure relief port. If the power source is a heat dissipation fan, the wind force can be applied to the second plate member through the air flow to realize the auxiliary opening of the baffle, so that the high-pressure gas in the cooking cavity can be completely emptied and maintained in a low-pressure state. In addition, using the heat dissipation fan as the power source can assist the baffle in relieving pressure while ensuring the heat dissipation of the device. On the one hand, it improves the utilization efficiency of the internal space structure of the cooking device, and on the other hand, the cooling of the heat dissipation fan also has the effect of cooling and relieving pressure, improving the efficiency of the device's pressure relief.

[0027] 3. For the cooking device provided by the present invention, the exhaust duct includes: a base pipe, with an annular concave portion provided on the circumferential side of one end, and the concave portion is clamped and sealedly fixed to the inner wall of the cooking cavity; a top pipe, fixedly connected to the other end of the base pipe, including a bearing surface extending circumferentially and arranged in a planar shape, and the bottom side of the bearing surface abuts against the steam storage cavity.

[0028] The exhaust duct is fixed to the cooking cavity through the concave portion on the base pipe and abuts against the steam storage cavity through the bearing surface, realizing the fixed connection with the cooking cavity and the steam storage cavity, ensuring the distance between the cooking cavity and the steam storage cavity, playing an auxiliary supporting function, and improving the stability of the cooking device.

[0029] 4. For the cooking device provided by the present invention, an annular enclosing plate is provided on the circumferential side of the base pipe.

[0030] The setting of the annular enclosing plate improves the strength of the exhaust duct, plays a role of fixed support, effectively improves the stability of the cooking device, and on the other hand, improves the connection stability between the concave portion and the cooking cavity, avoiding the occurrence of situations such as unclamping due to vibration or deformation of the cooking cavity wall, which affects the sealing performance.

[0039] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] As Figure 1 - Figure 2 , this embodiment provides a cooking device, including a steam storage cavity 1, an exhaust duct 2 and a pressure relief assembly. In this embodiment, the cooking device is a steam oven, but is not limited to cooking devices such as steamers, ovens, and steam pots.

[0041] A box door is provided outside the steam storage cavity 1, and a cooking cavity 11 is built inside. A first exhaust port is provided at the top of the cooking cavity 11. The inner top wall and the inner side wall of the steam storage cavity 1 are respectively spaced from the outer wall of the cooking cavity 11. A cavity for accommodating a cooling fan is provided on the steam storage cavity 1, and the opening of the cavity faces the position of the pressure relief component. As a variable implementation, the cavity can also be not provided, and the air outlet direction of the cooling fan can be set to face the bearing position of the pressure relief component.

[0042] In this embodiment, the exhaust duct 2 is fixedly connected to the cooking cavity 11 and the steam storage cavity 1 respectively, and a cylindrical channel is provided inside. One end is the outer end part, which is fixedly connected to the steam storage cavity 1 and leads to the outside through the second exhaust port on the steam storage cavity 1; the other end is the inner end part, which is connected to the position of the first exhaust port and leads to the inside of the cooking cavity 11, and can discharge the gas in the cooking cavity 11 to the outside. The opening of the outer end part is the pressure relief port 21. As a variable implementation, the exhaust duct can be only fixedly connected to the cooking cavity 11, and its outer end part can be arranged in structures such as a partition cavity and communicated with the outside through a duct.

[0043] The pressure relief component includes a baffle 3 and a fixing part 4. In this embodiment, the baffle 3 is an elastic part. As a variable implementation, the baffle 3 can be a non-elastic part and is movably connected to the fixing part, can rotate around the fixing part, and abuts against the top side pressure relief port 21 of the exhaust duct 2 under the action of gravity.

[0044] The baffle 3 is arranged on the outer end part of the exhaust duct 2, can block the pressure relief port 21 of the exhaust duct 2, and has a closed state of abutting against the pressure relief port 21 and an exhaust state of leaving the pressure relief port 21 under the action of an external force. By arranging the baffle 3 at the outer end part of the exhaust duct 2 to block the exhaust duct 2, excessive leakage of heat in the cooking cavity 11 is avoided, the thermal efficiency of the device is improved, the temperature uniformity of the whole cooking device is ensured, and the temperature point below the pressure relief port 21 is prevented from being too low, resulting in inconsistent cooked degrees of food and affecting user consumption. In addition, the opening and closing of the pressure relief port 21 are controlled through the baffle 3, and the structure is simple and the stability is high.

[0045] The fixing part 4 is arranged on the outer end part of the exhaust duct 2 and is fixedly connected to the baffle 3. The fixing part 4 includes a connecting part 41 and a fixing pin 42.

[0046] The connecting part 41 is in a plate shape, protrudes from the outer end part of the exhaust duct 2 in the opposite direction, and is perpendicular to the outer end part of the horizontally arranged exhaust duct 2. The fixing pin 42 is in a cylindrical shape, is arranged on the side of the connecting part 41, is perpendicular to the connecting part 41 and extends in the opposite direction of the connecting part 41, is parallel and spaced from the outer end part of the exhaust duct 2, and is fixedly connected to the baffle 3. The thickness direction of the connecting part 41 is perpendicular to the extending direction of the baffle 3, and the thickness direction is the extending direction of the fixing pin 42.

[0047] The baffle 3 is in the shape of a sheet with a bend, and includes a first plate member 31, a second plate member 32, and a third plate member 33 that are integrally formed.

[0048] The first plate member 31 is in the shape of a square sheet, and the shadow area projected on the outer end of the exhaust duct 2 is larger than the opening area of the pressure relief port 21. It can abut against the pressure relief port 21 in a closed state and completely cover the pressure relief port 21.

[0049] The second plate member 32 is fixedly connected to the first plate member 31 and extends towards the fixing part 4.

[0050] The third plate member 33 is in a rolled shape. One end is integrally formed with the second plate member 32, and the other end is wound around the fixing pin 42 and fixedly connected to the fixing pin 42. As an alternative embodiment, the third plate member may not be provided, and the second plate member may be directly fixed to the fixing pin.

[0051] The cooking device further includes a power source 5, which is provided on the side of the fixing part 4 different from the baffle 3 and can apply a deforming force to the second plate member 32 to make the first plate member 31 connected to the second plate member 32 move away from the pressure relief port 21. In this embodiment, the power source 5 is a cooling fan, which is provided in the cavity for accommodating the cooling fan. The cavity includes an air outlet 51, and the air outlet 51 is arranged towards the second plate member 32. The specific form of the power source is not limited, as long as it can assist in opening the baffle. As an alternative embodiment, the power source can also be a magnetic source such as an electromagnet, which is provided on the top side of the baffle.

[0052] When the steam reaches a certain pressure, the steam will drive the baffle to perform an upward tilting action. At this time, the force generated by the power source and the steam together will lift the baffle, thereby ensuring the normal pressure relief. The setting of the power source can apply a force to the second plate member to make the first plate member connected to the second plate member move away from the pressure relief port. If the power source is a cooling fan, the wind force can act on the second plate member 32 through the air flow to realize the auxiliary opening of the baffle 3, so that the high-pressure gas in the cooking cavity 11 can be completely emptied and maintained in a low-pressure state. In addition, using the cooling fan as the power source 5 can not only ensure the heat dissipation of the device but also assist in the pressure relief of the baffle 3. On the one hand, it improves the utilization efficiency of the internal space structure of the cooking device, and on the other hand, the cooling of the cooling fan also has the effect of cooling and pressure relief, improving the pressure relief efficiency of the device. The steam flowing out through the pressure relief port 21 will further flow towards the direction of the door under the drive of the power source 5. The second exhaust port is arranged above the door. Part of the steam condenses at the door position and is recycled, and the remaining steam that has not been completely condensed will flow out to the outside atmosphere through the second exhaust port.

[0053] As Figure 2 shown, the exhaust duct 2 includes a base pipe 22, a top pipe 23, and an annular enclosure 24.

[0054] An annular concave portion 221 is provided on the circumferential side of the bottom end of the base pipe 22. The concave portion 221 is clamped with the inner wall of the cooking cavity 11, and the end of the inner wall is bent and fixedly sealed.

[0055] The top pipe 23 is fixedly connected to the other end of the base pipe 22, and includes a bearing surface 231 that extends circumferentially and is arranged in a planar shape. The bottom side of the bearing surface 231 abuts against the steam storage cavity 1. The top pipe 23 and the base pipe 22 are detachably connected by threads.

[0056] The exhaust duct 2 is fixed to the cooking cavity 11 through the concave portion 221 on the base pipe 22 and abuts against the steam storage cavity 1 through the bearing surface 231, so as to realize the fixed connection with the cooking cavity 11 and the steam storage cavity 1, ensure the distance between the cooking cavity 11 and the steam storage cavity 1, play an auxiliary support function, and improve the stability of the cooking device.

[0057] An annular enclosure 24 is provided on the circumferential side of the base pipe 22. The provision of the annular enclosure 24 improves the strength of the exhaust duct 2, plays a role of fixed support, effectively improves the stability of the cooking device, and on the other hand improves the connection stability between the concave portion 221 and the cooking cavity 11, avoiding the occurrence of situations such as disengagement that affect the sealing performance due to vibration or deformation of the wall of the cooking cavity 11.

[0058] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
