Abstract

PURPOSE:To effectively utilize inexpensive midnight power while saving time for operation by executing such automatic control as to shift energizing time to a reduced rate time zone on the basis of a measured value by a sensor. CONSTITUTION:An energizing condition setting part 8 sets a condition for energizing by making a using condition such as room temperature or hot water temperature detected by a temperature sensor 4 and reduced rate time set in a reduced rate time setting part 7 as factors. An energizing propriety deciding part 9 decides the propriety of energizing by comparison with an energizing condition set in the energizing condition setting part 8 on the basis of the detection value of the temperature sensor 4 and present time information by a clock part 6. Then, a switch 3 opens or closes a load circuit on the basis of the decision of the propriety of the energizing. Thus, at the time of the operation of an apparatus, the discount system of the midnight rate can be automatically utilized to the maximum without spending any human labor.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention:: Based on the application of the time-of-day electricity rate system,
'M during the discount rate time period where electricity rates are cheaper! Electricity equipped with an energization control device and error device that automatically controls energization to match the specific gravity ratio! This is related to I equipment.

[Conventional technology]

BACKGROUND ART Conventionally, as a power rate system for utilizing electric power for -m households, a late-night power rate system in which electric water heaters are the main load has been known.

However, this late-night electricity rate system only applies to heat storage devices such as electric water heaters, and it also requires special wiring to be installed for load equipment such as electric water heaters.
However, the lighting circuits that power general home appliances were not covered by the low-cost late-night electricity system.

In the following, an electric stove will be described as an example of the prior art.

Figure 4 is a schematic electrical circuit diagram of an electric stove, where 10 is a power plug for connecting to a normal household outlet, 11
Is body sui Sochi, 12 is released #lil! The next day, it generates heat only when the device switch 11 is turned on! s12 is energized,
Heating takes place.

[Problem to be solved by the invention]

Next, problems with the prior art will be described using an example of using an electric stove having the above configuration in a bedroom.

The electric stove you are currently using has a heating capacity that takes 1 to 2 hours to reach room temperature depending on the room temperature conditions, and the late-night rate period when you can receive cheaper electricity rates is from 11pm to 7pm. The problems in making the most of the discount system are as follows, assuming that it is 8 hours until the end of the day, and that the bedtime is 0 o'clock.

First, there is a basic problem in that it takes time and effort to go to the bedroom and turn on the appliance switch 11 in advance every day.

In addition, we also set the energization start time, such as how many hours in advance to turn on the device switch 11 depending on room temperature conditions, and how to shift the energization time to the late-night charge period as much as possible to use it economically. was a troubling problem.

In the former case, if you want to automatically turn on the device switch 11 every day, there is a time switch, but since it does not take into account room temperature etc., it is a uniform control, so it does not matter whether it is for safety or comfort. Either one had to be sacrificed nine times.

The time-of-day electricity rate system, which is scheduled to be introduced in the near future, is intended to cover the lighting circuits that power ordinary home appliances. The aim is to proactively shift the operating hours of the equipment to late-night tariff hours when cheaper electricity rates are applied, and to automatically control the operation of the equipment without requiring any human effort. An energization control device according to the present invention includes: a clock unit for outputting time information; a discount rate time setting unit in which a discount rate application time specified by the electric power system is set; temperature,
A sensor for detecting humidity or gas, etc., an energization condition setting section for setting conditions for energization using the detected value of this sensor and time information as elements, and energization conditions for the detected value of the sensor and time information. Equipped with an energization propriety determination section for determining whether or not to energize based on comparison with the energization condition of the setting section, and a switch section that is controlled to open and close based on the judgment of the energization propriety determination section. It is.

[Effect]

The energization control device according to the present invention controls the operation of electrical equipment based on the determination of the energization propriety determination unit, which has conditions set to preferentially allocate energization time to discount rate hours based on the detected value by the sensor. Because the operation of electrical equipment is performed automatically, the ratio of operating electrical equipment that is eligible for cheaper electricity rates increases, resulting in economical effects such as lower electricity charges, and because operation control is performed automatically, there is a labor-saving effect in operating equipment. have
