The present invention focuses on this point and solves the above-mentioned problems. In claim 1, the invention operates the device using various lighting contracts such as a late-night power system and a time-based lighting contract system. A storage means for storing a plurality of time zone operation patterns in advance for each light contract, and reading out the necessary time zone operation patterns from the storage means, and controlling as a device operation reference. Setting means for storing in the means.
[0006]
This ensures that the equipment can be operated in accordance with the lighting contract signed with the power company, and that the settings are made very easily by selecting from multiple time zone operation patterns. It is possible to operate the equipment at a low electricity rate, it is very economical, and the running cost can be greatly reduced.
[0007]
According to the second aspect of the present invention, since the display means for displaying the stored time zone operation pattern is provided, it is possible to visually confirm the contracted operation pattern, and to use it in an expensive time zone without knowing it. Is surely prevented, and a sense of value can be appealed.
[0008]
According to the third aspect of the present invention, the display means makes one lap a day, divides the one lap into a plurality of tracks, turns on or off a low-cost time zone as an operable time, and displays an expensive or normal charge time. Since the belt is turned off or lit as the operation prohibition time and displayed in reverse to each other, the operable time and the operation prohibition time can be known at a glance, and erroneous operation can be reliably prevented.
[0009]
According to the fourth aspect of the present invention, since there is provided a change means for appropriately reading out the time zone operation pattern before or after the storage and changing it together with the display, it is necessary to store all the different power contracts at each power company. It can be easily changed from the basic time zone operation pattern, and even if the time or fee changes in the middle, the display can also be changed at the same time, so the change can be made securely while looking at the display The usability is extremely good.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a remote controller for an electric device such as a heat pump water heater that is operated under a light contract with each electric power company. The remote control 1 includes an operation unit 2 including a plurality of operation switches and a display unit 3 such as a liquid crystal display.
Reference numeral 4 denotes control means including a microcomputer for controlling the operation of each drive component according to the detection values of various sensors.
[0011]
Reference numeral 5 denotes an operation switch provided in the operation unit 2 for controlling start and stop of operation, and 6 denotes a setting switch for setting an operation standard of the device in accordance with a light contract signed with an electric power company. The mode is entered, a matching one of a plurality of time zone operation patterns stored in advance in the storage means 7 is sequentially displayed and selected by the up switch 8 and the down switch 9 and determined by pressing the determination switch 10. The setting means 11 is composed of a setting switch 6, up / down switches 8, 9 and a decision switch 10.
[0012]
Reference numeral 12 denotes a change switch which constitutes a change means for changing the time of the time zone operation pattern corresponding to each electric power company. The up / down switches 8 and 9 are based on the closest time zone operation pattern by the setting means 11. The time is changed.
[0013]
Numeral 13 denotes a time zone operation pattern display means, with one lap as one day, a 24-segment display lamp in the form of a truck, turning on the cheap time zone as the operable time, and extinguishing the overtime or normal fee time zone as the driving prohibited time. Is displayed.
[0014]
Next, the operation of this embodiment will be described. In order to cause the control means 4 to input a light contract signed with a local power company as an operation reference, pressing the setting switch 6 results in an operation reference setting mode. Each time the up switch 8 is pressed, the display means 13 shown in FIGS. 3, 4 and 5 is displayed on the display unit 3 in order, and when the down switch 9 is pressed, the display is performed in the reverse order.
[0015]
That is, FIG. 3 shows a first time zone operation in which only the period between PM 11:00 and AM 7:00, which is a cheap time zone under the hourly light contract system, is the operable time A (the shaded portion in the figure indicates the lighting state). FIG. 4 shows a pattern in which the driving is prohibited only in the daytime, which is an expensive time zone in the same time zone lighting contract system, and the operable time A is between 5:00 PM and 10:00 AM, which is the other time. FIG. 5 is a third time zone operation pattern in which the operable time A is from 11:00 to 8:00 PM, and these three time zone operation patterns are stored in the storage means 7 in advance. That's what you'll let me do.
[0016]
Then, from the three time zone operation patterns, the one that matches the electric light contract and most closely matches the life pattern of the user himself is selected, and when the confirmation switch 10 is pressed, the time period operation pattern is determined. Then, it is stored in the control unit 4 and displayed on the display unit 3 as the display unit 13.
[0017]
Further, the control means 4 controls the operation so as to operate only within the predetermined time zone operation pattern, except when there is a possibility that hot water may be insufficient. Since the hot water is kept at a high temperature until the night by boiling the hot water at a low electricity rate, the heating is controlled so as to end the heating as close to the end of the cheap time zone as possible.
[0018]
Next, when there is no contracted time zone in the three time zone operation patterns, or when there is a change in the contract time, etc., the setting switch 6 is pressed, and then the up / down switches 8 and 9 are pressed. When the closest time zone operation pattern is selected and the change switch 12 is pressed, the time change mode is established and the set time of the selected time zone operation pattern is increased while looking at the display means 13. It can be changed with the down switches 8 and 9, and is automatically determined without any operation for 5 seconds.
[0019]
Therefore, the electric equipment can be controlled in accordance with the light contract with the electric power company, and the running cost can be surely reduced. In addition, the light contract can be visually confirmed on the display means 13, and the user himself / herself can be confirmed. Savings in energy savings and higher economic effects can be obtained. In addition, the time zone operation pattern can be changed freely, so it is easy to respond to new lighting contracts or changes in the middle of the operation, making it extremely easy to use. Is a good one.
[0020]

It can be operated at low electricity rates, is extremely economical, and can greatly reduce running costs.
[0021]
According to the second aspect of the present invention, since the display means for displaying the stored time zone operation pattern is provided, it is possible to visually confirm the contracted operation pattern, and to use it in an expensive time zone without knowing it. Is surely prevented, and a sense of value can be appealed.
[0022]
According to the third aspect of the present invention, the display means makes one lap a day, divides the one lap into a plurality of tracks, turns on or off a low-cost time zone as an operable time, and displays an expensive or normal charge time. Since the belt is turned off or lit as the operation prohibition time and displayed in reverse to each other, the operable time and the operation prohibition time can be known at a glance, and erroneous operation can be reliably prevented.
[0023]
According to the fourth aspect of the present invention, since there is provided a change means for appropriately reading out the time zone operation pattern before or after the storage and changing it together with the display, it is necessary to store all the different power contracts at each power company.
