Dependent claims

A household electric appliance with a high-low pressure function, comprising a high-low pressure forming apparatus, wherein the high-low pressure forming apparatus comprises a movement apparatus, a pressure forming rod, a pressure forming body, a pressure forming shell and a valve, wherein the valve comprises a pressure suction valve and a pressurization valve, and the high-low pressure forming apparatus is a device for manufacturing a high-pressure compartment or a low-pressure compartment of the household electric appliance with the high-low pressure function;

wherein an outer periphery of a bottom of the pressure forming shell of the high-low pressure forming apparatus is integrally provided with or coupled with the pressurization valve for manufacturing a pressure higher than an atmospheric pressure and the pressure suction valve for manufacturing a pressure lower than the atmospheric pressure;
wherein the high-low pressure forming apparatus is integrally provided with or coupled with the household electric appliance with the high-low pressure function, and the pressure forming shell is integrally provided with or coupled with the high-low pressure forming apparatus, wherein an inner side of the pressure forming shell is provided with the pressure forming body which reciprocates axially along a hole wall in the pressure forming shell, the pressure forming body is integrally provided with or coupled with the pressure forming rod in a movable fit manner, the other end of the one pressure forming rod is integrally provided with or coupled with a transmission apparatus in a movable fit manner, and the transmission apparatus is integrally provided with or coupled with a power apparatus;
and
wherein when the pressure forming body axially reciprocates along the hole wall in the pressure forming shell to a position where space between the pressure forming body in the pressure forming shell and a bottom cover of the pressure forming shell reaches the maximum and contains maximum amount of gas, the pressure forming body compresses space of internal gas to form a high pressure, or when the pressure forming body axially reciprocates along the hole wall in the pressure forming shell to a position where space between the pressure forming body in the pressure forming shell and a bottom cover of the pressure forming shell reaches the minimum and contains minimum amount of gas, the pressure forming body expands space of internal gas to form a low pressure.
