no. 1 Embodiment approach ）

[0023] figure 1 It is a perspective view of the elevator according to the first embodiment of the present invention. The elevator involved in the present embodiment includes: an elevator passage 10; a car 12 that is raised and lowered by a pair of guide rails 11 provided in the elevator passage 10; The counterweight 16 of the counterweight body 15 . The elevator includes: a sheave 17 around which a cable 14 is wound; and a motor 18 for rotating the sheave 17 .

[0024] figure 2 It is the composition diagram of the elevator. The above-mentioned reference numerals denote the same elements. The elevator according to this embodiment includes: a power conversion unit 19 that supplies motor driving power to the motor 18; up and down. The traction machine 20 has a sheave 17 and a motor 18 . The elevator is equipped with: an elevator control unit 21, which drives and controls the traction machine 20, and switches the elevator operation between normal operation and energy-savin...

no. 2 Embodiment approach ）

[0055] In the above-mentioned first embodiment, the server device 24 collects the time-average power amounts from all the elevators, and obtains an added average for the entire elevators. The elevator according to the second embodiment of the present invention displays energy-saving effect information without performing transmission and reception with the server device 24 . The elevator compares the current state of its own car with the past state of its own car in its own car. The elevator displays the energy-saving effect information at the current moment. The elevator involved in this embodiment does not pass figure 2 The communication portion of the network 54 and / or the server device 24 communicates. The elevator involved in this embodiment replaces figure 2 The calculation unit 26 of the elevator, and for example, the elevator control unit 21 in the elevator is equipped with other calculation units having the calculation function described below. Regarding other as...

Abstract

The invention provides an elevator which solves the problems that energy-saving effect information cannot be displayed on a display device in an elevator cab and / or at an entrance to the elevator cab and energy-saving effects cannot be shown to passengers. The elevator includes a cab; a balance weight; a traction machine; an elevator control unit switching between usual operation and energy-saving operation achieved through separation of a counterweight; an electric power meter which measures the obtained amount of electric power by all power consumption by a plurality of loads including the traction machine; a recording unit which records the amount of electric power and time information, records a plurality of time periods divided according to the time information and reflects the average amount of electric power of the amount of electric power reduction obtained by energy-saving operation according to each time period; a calculating unit which conducts comparison operation of data on the average amount of electric power in a time sequence and data on the demanding amount of electric power according to variations in each time period; and a display unit which displays, according to the comparison result, the energy-saving effect information on the average amount of electric power obtained through energy-saving operation, and is arranged at a display portion in the cab and an entrance on each floor.

Description

technical field [0001] The present invention relates to elevators, and more particularly to elevators that perform energy-saving operation that reduces power consumption. Background technique [0002] Conventionally, there is known an elevator that balances the weight of the car and the counterweight to reduce power consumption (see, for example, Patent Document 1). As an elevator that performs energy-saving operation, there is known an elevator power display device that displays the amount of power saved by the elevator to a manager (see, for example, Patent Document 2). There is known an energy-saving promotion system that displays energy-saving promotion information on a user's display terminal (see Patent Document 3).
