Abstract: An air-conditioner (10) is provided, including a casing (12), an evaporator (14), a front panel (16) and a temperature sensor (18). The casing (12) has an air inlet (120) and an air outlet (122). The evaporator (14) is arranged in the casing (12). The front panel (16) is arranged in front of the casing (12). The temperature sensor (18) is disposed to a back of the front panel (16) and is used for sensing an ambient temperature.

Abstract: This invention relates to a kind of electric iron for eliminating wrinkles from clothes and other materials. The electric iron has an ironing seat, which is composed of a soleplate, an ironing surface on the soleplate, and a heater that heats the soleplate. There are heater-shaped dented portions on the ironing surface where the heater is installed. This invention, with this structure, reduces a contacting area between the ironing surface close to the heater and clothes or other materials to be ironed, thus changing an uneven distribution of temperature on the ironing surface. Further, for a steam electric iron, steam sprayed out of steam outlets in a soleplate spreads to areas away from a heater through dented portions, thereby resulting in an effect of wrinkle elimination.

Abstract: This invention relates a kind of electric iron for eliminating the wrinkles on clothes and some other materials. The electric iron has an ironing seat, which is composed of soleplate, ironing surface on the soleplate, and heater that heats the soleplate. There are heater-shaped dents on the ironing surface where the heater is installed. This invention, with the said structure, reduces the contacting area between the ironing surface close to the heater and the clothes or other materials, thus effectively changing the uneven distribution of temperature on the ironing surface. Further, for steam electric iron, the steam sprayed out of the steam outlets in the soleplate spreads to areas away from the heater through the dents, resulting to excellent effect of wrinkle elimination.
