A cooking appliance 100 in accordance with an embodiment of the present invention is described below with reference to Figures 1-5.

As shown in FIG. 1, a cooking appliance 100 according to an embodiment of the present invention includes a pot body 10 and a lid 20.

Wherein, the cross section of the pot body 10 has a long axis and a short axis orthogonal to each other, the pot body 10 includes an outer pot 11 and an inner pot 12, the inner pot 12 is located in the outer pot 11, and the upper pot of the outer pot 11 is configured with an outer pot On the outer flange 111, the lid 20 is disposed on the pot body 10. The cross section of the lid 20 is adapted to the shape of the cross section of the pot body 10. The lid 20 includes an outer lid 21, and the edge of the outer lid 21 has a downward direction. The extending side wall 212, the bottom end portion of the side wall 212 is press-fitted on the outer pot outer flange 111 by a self-weight; the sealing ring 23 is placed on the top of the inner pot 12 and the outer cover 21 between.

According to the cooking appliance 100 of the embodiment of the present invention, by using the top end of the outer pot 11 to support the gravity of the outer cover 21, the sealing ring 23 is prevented from being squeezed by the gravity of the outer cover 21, ensuring the non-cooking state. The lower seal ring 23 has a movable gap in the vertical direction to achieve dynamic sealing, which provides sufficient free expansion space for the seal ring 23 compared to the cooking appliance 100 of the related art, further improving the sealing property of the cooking appliance 100.

Specifically, the lower edge of the side wall of the outer cover 21 is configured with an outer cover outer flange 212. The outer cover outer flange 212 is supported on the outer outer flange 111, and the inner cover 22 is disposed in the outer cover 21, and the sealing ring 23 is sleeved. On the inner cover 22, in this way, the outer cover 21 is stopped by the outer girth 212 of the outer cover against the outer surface of the outer pan outer edge 111 by its own gravity.

The present invention utilizes the top end of the outer pot 11 to support the side wall of the outer cover 21, so that the outer cover 21 is self-reset on the outer pot 11, that is, the outer pot 11 is used to support the gravity of the outer cover 21, in a non-cooked state. Next, the outer cover 21 does not press the sealing ring 23 by gravity, thereby ensuring that the sealing ring 23 has a gap that moves up and down in the non-cooking state, and the deformation of the sealing ring 23 occurs when the temperature and pressure of the lid 20 rises. Since the sealing ring 23 forms a dynamic seal due to the gap between the upper and lower movements, the sealing ring 23 has a space for free expansion inside the lid 20, thereby achieving a better sealing effect.

According to an alternative embodiment of the present invention, the outer circumference of the sealing ring 23 has a gap with at least one of the outer cover 21 and the inner pot 12, and the sealing ring 23 serves to seal the gap between the outer cover 21 and the pot body 10, Prevent leaks.

The sealing ring 231 is arranged in a closed loop shape, and the first skirt 232 and the second skirt 233 are respectively The sealing ring edge 231 is disposed along the axial direction of the sealing ring edge 231. When the sealing ring 23 is sleeved on the inner cover 22, the outer peripheral edge of the inner cover 22 is wrapped around the sealing ring edge 231 and the first skirt. Between the side 232 and the second skirt 233.

Specifically, the first skirt 232 is located above the second skirt 233, and the first skirt 232 cooperates with the second skirt 233 to seal the gap between the outer cover 21 and the inner pot 12, and the sealing ring 231 and the outer At least one of the cover 21 and the inner pot 12 has a gap, so that a space is left for the free expansion of the seal ring 23, so that the seal ring 23 can ensure the stability of the lid 20 and the pot body 10 to prevent the occurrence of steam leakage.

As shown in FIG. 1 , the lid 20 further includes a pair of clamps 30 disposed on the outer cover 21 and adjacent to and away from each other. Further, the lid 20 is further provided on the lid 20 The control device is configured to control the opening and closing of the pair of clamps 30. Specifically, the control device controls the pair of clamps 30 to close, and the pair of clamps 30 are close to each other to fasten the outer pot 11 so that the lid 20 can be locked Tightly on the pot body 10, at this time, the lid 20 covers the pot body 10, and the control device controls the pair of grippers 30 to open, and the pair of grippers 30 are separated from each other and separated from the outer pot 11 for opening the lid 20, By providing a pair of clamps 30 on the outer cover 21, the lid 20 can be snapped together with the outer edge of the outer pot 11, so that the connection of the lid 20 to the pot 10 is more reliable.

As shown in FIG. 2 and FIG. 3, optionally, the outer peripheral edge of the outer cover 21 is provided with a pressure receiving step 211, and the upper edge of the inner pot 12 is provided with an inner pot outer flange 121, and the inner pot outer flange 121 is under pressure. Below the step 211, the seal ring 231 is located between the pressure step 211 and the inner pot outer edge 121. The pressure step 211 supports the clamp 30, and the seal ring 231 and the pressure step 211 and the inner pot are turned outward. At least one of the sides 12 has a gap, and there is a gap between the seal ring side 231 and the pressure step 211 and the inner pot outer turn 12 in FIG. 3 to ensure that the seal ring 23 has a freely expanding space inside the lid 20.

As shown in FIGS. 4 and 5, further, the thickness of the seal ring 231 is smaller than the distance between the pressure step 211 and the outer flange 12 (the distance shown in the vertical direction in FIG. 5), so that the seal is The ring 231 has a gap with at least one of the pressure receiving step 211 and the inner pot outer flange 12.

Specifically, the thickness of the seal ring 231 is denoted by d, and the distance between the pressure step 211 and the outer flange 12 is represented by h, wherein 0.5 mm < dh < 4 mm, and the difference between d and h is 0.5 mm. Between 4mm, specifically, it can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, etc., according to the actual situation, by limiting the difference between d and h within the above range to ensure There is a free expansion space in the vertical direction of the sealing ring 23 within the lid 20.

As shown in FIG. 5, optionally, the seal ring 231 has a gap with the side wall of the outer pot 11 in the horizontal direction, that is, the outer periphery of the seal ring 231 is spaced apart from the side wall of the outer pot 11 in the horizontal direction. In order to ensure the free expansion space of the sealing ring edge 231 in the horizontal direction.

Specifically, the distance between the sealing ring edge 231 and the side wall of the outer pot 11 in the horizontal direction is represented by s, wherein 1 mm < s < 4 mm, that is, s is between 1 mm and 4 mm, and may be 1.5 mm, 2mm, 2.5mm, 3mm, 3.5mm, etc., which are set according to actual conditions, by limiting s within the above range, to ensure a free expansion space of the seal ring 23 in the horizontal direction in the lid 20.

Referring to Fig. 1, the cross section of the lid 20 and the cross section of the pot body 10 are respectively formed into an elliptical shape which is adapted to each other to satisfy the user's demand for cooking long-shaped foods such as poultry, fish, ribs, etc., and the user experience is good.
