This invention discloses a vortex water tank with a constant temperature extrusion die, comprising a tank body, end plates fixed to both ends of the tank body, a sealing plate dividing the inner cavity of the tank into a vacuum section and a non-vacuum section, a top cover rotatably connected to the top of the tank body, and a sealing seat disposed in the non-vacuum section. The sealing seat has a through hole for the profile to pass through, and a water seal structure for forming a dynamic water seal is provided in the through hole. It also includes an extension cover, fixedly connected to the side of the sealing seat near the non-vacuum section, with its end rotatably connected to the sealing plate via a rotating shaft. By automatically releasing the sealing plate and opening the channel, the profile head can be smoothly output under the protection of the formed complete water seal. This avoids poor profile head shaping, dimensional fluctuations, and surface defects caused by insufficient vacuum or incomplete water seal establishment, thereby minimizing the waste length during startup and significantly improving material utilization and startup yield.

The utility model provides a hinge assembly and contain its refrigerator. Hinge assembly is used for the opening and closing of the door body of refrigerator, and hinge assembly includes: hinge, hinge is six connecting rod mechanism and includes first connecting rod member, second connecting rod member, third connecting rod member and sixth connecting rod member, first connecting rod member is hinged with second connecting rod member and third connecting rod member respectively, and the position of first connecting rod member and second connecting rod member, third connecting rod member hinged is first hinged position and second hinged position respectively, and electric actuating device, input end is used for connecting external power supply, and output end is used for outputting rotary motion and is used for acting on first hinged position or second hinged position, to make second connecting rod member or third connecting rod member rotate. The hinge assembly can realize automatic unfolding and folding through electric actuating device, so that the refrigerator including hinge assembly can realize automatic opening and closing, and need not manual operation, and use is more convenient.
