Title:
COLD AND HEAT ISOLATION APPARATUS AND ISOLATION VALVE ASSEMBLY OF FOOD COOKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082240
Kind Code:
A1
Abstract:
In a food cooking device (1), a cold and heat isolation apparatus and an isolation valve assembly (230) thereof, a first air vent (232) is switched on and off by moving a butt-joint base (231) opposite to a heat insulation valve core (233). An elastic pre-tightening member (239) directly or indirectly acts on the heat insulation valve core (233), and provides a pre-tightening force for causing the heat insulation valve core (233) to abut against the butt-joint base (231) to the heat insulation valve core (233). The elastic pre-tightening force enables the heat insulation valve core (233) to better fit the butt-joint base (231), thereby improving the sealing effect of the heat insulation valve core (233) and the first air vent (232). Due to the presence of the elastic pre-tightening member (239), the heat insulation valve core (233) can adaptively adjust the position according to the structure of the surface of the butt-joint base (231), and even if the outer surface of the butt-joint base (231) is uneven due to the machining technology and other reasons, the heat insulation valve core (233) can also stably move relative to the butt-joint base (231), which reduces the requirement for the machining precision of the outer surface of the butt-joint base (231), and is beneficial to reducing the machining cost.
