Abstract: A steam cleaner comprises a water reservoir; a heater including a supply pipeline, a first steam pipeline spaced from the supply pipeline, and a sediment catching space between the supply pipeline and the first steam pipeline; a steam chamber with a portion of the first steam pipeline disposed therein; and a nozzle including a second steam pipeline partially disposed in the steam chamber and spaced from the first steam pipeline. Water is drawn out of the water reservoir to the heater for heating, steam is generated in the heater and flows out of the supply pipeline into the first steam pipeline through the sediment catching space with solid particles therein being deposited in the sediment catching space to form sediment and remaining steam flowing into the second steam pipeline through the steam chamber, and the steam is shot out from the nozzle. The invention prevents sediment from blocking the nozzle.

Abstract: The roaster includes two handles disposed at both sides of an upper portion of the roaster, two opposite racks respectively fixed at a front end and a rear end of the two handles, electric heating tubes arranged between the two handles, an oil-gathering pan located in a lower portion of the roaster, a guide tube disposed in an inner sidewall of the roaster and extending from an inner sidewall of one of the two handles to the oil-gathering pan, and a grill pan which is located on a top end of the roaster and of which bottom is connected with the guide tube so that excess oil and sauce remained in the grill pan will be guided through the guide tube into the oil-gathering pan, by which the grill pan is capable of being placed above and across the opposite racks of the two handles and being fixed at corresponding locations for grilling meat so as to fully using the inner and outer spaces of the roaster for achieving the multi-function of roasting and grilling in one roaster and saving electricity.
