In a preferred embodiment, as shown in fig. 2, the sealing portion 22 is bent and extended upward such that the upper edge of the sealing portion 22 is higher than the upper surface of the contact portion 21, and the cooling plate 3 is fixed above the inner cover 2 to form the cooling cavity 23 in cooperation with the upper surface of the contact portion 21.

The upper edge of the sealing part 22 is higher than the upper surface of the contact part 21, so that a positioning groove is formed at the contact part 21 and used for installing and positioning the cooling plate 3, when the cooling plate 3 is installed, the cooling plate 3 and the contact part 21 can be conveniently aligned and installed by limiting the stop of the sealing part 22 on the periphery of the contact part 21, so that the cooling plate 3 and the contact part 21 are coaxial, the assembly difficulty of the pot cover assembly is reduced, and the offset of the cooling plate 3 on the contact part 21 is avoided.

In the present embodiment, the cooling plate 3 is provided with a mounting opening 35 for the extension of the exhaust pipe 11 and the float valve 25.

Preferably, as shown in fig. 2, a side of the inner lid 2 facing the cooling chamber 23 is provided with a mounting groove 24, the mounting groove 24 having a mounting plane, and the blocking portion 33 being located in the mounting plane.

When the water in the cooling cavity 23 flows to the mounting groove 24, the water needs to fill the mounting groove 24 before flowing towards the water outlet 32 due to the height reduction, so that the contact time of the water and the inner cover 2 is increased, the contact area of the water and the inner cover is increased, and the heat exchange efficiency is improved. The blocking part 33 is located in the installation groove 24, and further blocks water entering the installation groove 24, thereby having a double blocking effect and improving a cooling effect.

In addition, the installation plane makes the installation and the cooperation of parts such as the exhaust pipe 11, the float valve 25 and the like simpler, and the sealing is completed by abutting with the sealing element 4 more easily, so that the sealing difficulty is reduced.

The utility model also discloses a pressure cooking appliance, which comprises a pot body, an inner container arranged in the pot body, and the water-cooling pot cover assembly, wherein the inner cover 2 and the inner container are matched and enclosed to form a cooking cavity in a state that the pot cover assembly covers the pot body, and the sealing part 22 is in abutting sealing with the opening edge of the inner container.

After the pressure cooking, the cooling chamber 23 is filled with cold water to cool the inner cover 2, so that the air pressure in the cooking chamber is reduced rapidly, and the quick uncovering of a user is facilitated. And cold water and the area of contact of inner cup 2 is big, and contact time is long, can take away more the heat of inner cup 2, and cooling efficiency is higher.

Preferably, the pot body is provided with a water cooling assembly such as a water tank, a water pump and the like, and the pot cover assembly is hinged with the pot body, so that the water cooling channel extends to the pot cover assembly through a hinged position. Of course, the pressure cooking appliance may be a split type, that is, the pot cover assembly may be removed from the pot body, and then the water tank, the water pump and the water cooling channel are disposed in the pot cover assembly, or still disposed in the pot body, and the pot cover assembly and the pot body are respectively provided with a coupling structure to realize the communication of the pot cover assembly and the circuit and/or the waterway of the pot body.

The utility model can be realized by adopting or referring to the prior art at the places which are not described in the utility model.

In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments.

The foregoing is merely exemplary of the present utility model and is not intended to limit the present utility model. Various modifications and variations of the present utility model will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the utility model are to be included in the scope of the claims of the present utility model.
