  • Publication number: 20240102718
    Abstract: Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.

  • Publication number: 20220331941
    Abstract: An electric working machine with the same or more prevention or suppression of the transmission of the vibration than that of a related art because of having the less components and the less man-hours for assemblies than those of the related art is achieved. A hammer drill includes a motor serving as a driving source and is equipped with a drill bit driven by a driving force that is output from the motor. The hammer drill includes a main-body housing and a handle housing forming at least a part of an outer shell, and the main-body housing and the handle housing are connected to each other through an elastic body to be relatively movable. The elastic body is formed on the main-body housing and the handle housing by a double-layer molding, and is a part of a continuous resin cover covering surfaces of the main-body housing and the handle housing.
