Abstract: An air conditioning device for a vehicle includes: a housing having an inside divided into an inflow space, a heat exchange space, and an outflow space, which are straightly arranged, and having a plurality of discharge ports, which communicates with an interior, at the inflow space; a blowing unit disposed at the inflow space of the housing and configured to blow air; a heat exchange unit disposed at the heat exchange space of the housing and configured to adjust a temperature of conditioned air by exchanging heat with air; and an opening-closing door disposed at the outflow space of the housing and configured to open and close the plurality of discharge ports such that conditioned air at an adjusted temperature selectively flows to the plurality of discharge ports. The air conditioning device adjusts the temperature of conditioned air for respective modes and reduces a flow resistance of air.

Abstract: Disclosed is an electronic range including a cavity, in which cooking of food is to be conducted, a heater chamber arranged over the cavity, an axial-flow fan arranged in the heater chamber and adapted to generate a downward flow of air, and a heater arranged outside the axial-flow fan and adapted to generate heat of a high temperature. A convection plate is arranged between the axial-flow fan and the heater. The convection plate serves to control a flow of air circulating in the interior of the electronic range to effectively convect the heat generated from the heater into the cavity during an operation of the axial-flow fan causing a repeated procedure of downwardly introducing the downward flow of air into the cavity, and then upwardly moving the flow of air along a side wall of the cavity. In this electronic range, food disposed in the cavity is heated, using reflection heat generated by the convection plates and convection air generated by the axial-flow fan.
