Based on the embodiments of the present invention described in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, an embodiment of the present invention provides a high pressure steaming cooking device, which includes an inner container 10 and a pressure relief mechanism 20. The inner container 10 is provided with a cooking cavity 30 therein, and the inner container 10 is provided with a pressure relief hole 101. The inner container 10 includes a top wall 11, a bottom wall 12, a left side wall 13, a right side wall 14 and a rear side wall 15, the top wall 11, the bottom wall 12, the left side wall 13, the right side wall 14 and the rear side wall 15 enclose to form a cooking cavity 30, the pressure relief hole 101 may be arranged on the top wall 11, of course, the pressure relief hole 101 is not limited to be arranged on the top wall 11, and may also be arranged on the left side wall 13 or the right side wall 14 as required according to different pressure relief positions. The pressure relief mechanism 20 includes an aperture plate 22, a cam 23, and a driving member 24, the aperture plate 22 has a first position (as shown in fig. 2, when the aperture plate 22 is in the first position) for shielding the pressure relief hole 101 and a second position (as shown in fig. 3, when the aperture plate 22 is in the second position) for opening the pressure relief hole 101 to communicate the cooking cavity 30 with the outside, the cam 23 is connected to the aperture plate 22, the driving member 24 is connected to the cam 23, and the driving member 24 drives the cam 23 to rotate to move the aperture plate 22 between the first position and the second position.

Foretell high pressure steaming cooking device makes the aperture plate 22 move between primary importance and second place through driving piece 24 drive cam 23, because aperture plate 22 shields pressure release hole 101 when the primary importance, and aperture plate 22 opens pressure release hole 101 when the second place with intercommunication culinary art chamber 30 and outside, emits the gas in the culinary art chamber 30, reduces the pressure in culinary art chamber, so, not only simple structure, equipment convenience, pressure release mode safe and reliable moreover.

The connection between the cam 23 and the escutcheon plate 22 is: contact connection is formed in a partial angle range. Specifically, the cam 23 has an outer contour having an arc-shaped guiding edge 231 with a radius R1 and an arc-shaped first edge 232 with a radius R2, the arc-shaped guiding edge 231 is connected to the arc-shaped first edge 232 by a tangent line, the connecting axis of the driving member 24 coincides with the center of the arc-shaped first edge 232, and the arc-shaped guiding edge 231 is mainly used for controlling the movement of the aperture plate 22, that is, the movement law of the aperture plate 22 is determined by the contour curve of the arc-shaped guiding edge 231. The outer contour of the well plate 22 can be connected by various circular arcs, specifically, the outer contour of the well plate 22 has an arc controlled edge 221 with a radius R3, where the arc controlled edge 221 is defined from a driving and driven perspective, that is, the arc controlled edge 221 is actually controlled by the arc guide edge 231. As the aperture plate 22 moves from the first position to the second position, the arcuate controlled edge 221 contacts the arcuate leading edge 231. Thus, the driving member 24 drives the cam 23 to rotate, and when the arc guiding edge 231 of the cam contacts the arc controlled edge 221 of the aperture plate, the aperture plate 22 can be pushed to move from the first position to the second position, so as to open the pressure release hole 101, release the gas in the cooking cavity 30, and reduce the pressure in the cooking cavity. That is, the cam 23 is in contact with the escutcheon plate 22 only during movement of the escutcheon plate 22 from the first position to the second position.

Illustratively, R1 < R3. In this way, it is ensured that the arc guide edge 231 smoothly contacts the arc controlled edge 221, thereby smoothly pushing the orifice cover plate 22 to open the pressure relief hole 101.

Illustratively, the aperture plate 22 may be hinged to the inner container 10, for example, by a screw connected to the top wall 11 of the inner container 10, and can rotate relative to the top wall 11, the aperture plate 22 can move from the second position to the first position under the action of gravity, and the arc-shaped controlled edge 221 is disengaged from the arc-shaped guiding edge 231 when the aperture plate 22 moves from the second position to the first position. Thus, after pressure relief, the cam 23 is driven by the driving member 24 to continue rotating, the arc guiding edge 231 of the cam is no longer in contact with the arc controlled edge 221 of the escutcheon plate, and the escutcheon plate 22 is no longer pushed by the cam 23, but moves from the second position to the first position under the action of gravity, and covers the pressure relief hole 101.

Illustratively, an elastic member 25 is attached to the escutcheon plate 22, and the elastic member 25 may be a tension spring that initially provides tension or no tension to the escutcheon plate 22. In order to conveniently arrange the elastic member 25, the aperture plate 22 is provided with an elastic member connecting hole 222, and a hook at one end of the elastic member 25 passes through the elastic member connecting hole 222 to be fixed, so that the elastic member 25 is convenient to disassemble and is convenient to maintain. The resilient member 25 provides damping to the escutcheon plate 22 when the arcuate controlled edge 221 contacts the arcuate guide edge 231, thereby preventing the escutcheon plate 22 from being impacted by the cam 23, causing a bullet to fly and then fall down on the cam 23, damaging the driving member 24, and preventing the cam rotation rate from being influenced by gravity, which is within a controllable range.

Illustratively, the arcuate leading edge 231 subtends an angle θ of 30 ° -90 °. Since the arc-shaped controlled edge 221 contacts the arc-shaped guiding edge 231 to push the aperture plate 22 to move from the first position to the second position to open the pressure relief hole 101, this means that the opening time of the pressure relief hole 101 is controlled by the rotation angle of the arc-shaped guiding edge 231, the rotation angle of the arc-shaped guiding edge 231 is, for example, 30 °, 45 °, 60 °, 75 °, 90 °, and the applicant found that the arc-shaped guiding edge at such a rotation angle can allow the pressure relief of the cooking cavity at a proper pressure relief rate to achieve a perfect pressure relief effect.

By way of example, the drive member 24 is an electric motor. So, through the rotational speed of control motor, just can control the open time frequency of pressure release hole 101 to the pressure release rate in control culinary art chamber reaches perfect pressure release effect.

As another example, the drive member 24 may be a rotary hydraulic cylinder. So, through the rotational speed of control rotary hydraulic cylinder, just can control the open time frequency in pressure release hole 101 to the pressure release rate in control culinary art chamber reaches perfect pressure release effect.
