Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric hot water storage container capable of controlling boiling water according to a user's life time program.

[0002]

2. Description of the Related Art Generally, the hot water of an electric hot water storage container is, for example, for coffee in the morning, for tea in the daytime, for tea at 3:00 PM, and for tea in the evening, depending on the user's own lifestyle and life time. It is used for various purposes.

However, the optimum hot water temperature required in each of these time zones and the applications corresponding thereto is originally different from each other.

Therefore, a recent microcomputer type electric hot water storage container is provided with a timer function such as a "sleep timer" (often about 6 hours) and a temperature adjusting function to set a preset time. Some have been provided so that hot water at a desired temperature can be obtained by controlling the setting (for each living time zone) each time to keep hot water.

[0005]

However, morning, noon, and P
For each of M3 o'clock, evening, and even night,
Setting the temperature and time is very troublesome, and considering not only the heating time but also the cool down time, if the time between the set operation time and the target time is not long enough, hot water of the optimum temperature will be obtained. Hard to get.

In view of the above circumstances, the present invention provides an electric appliance which can automatically obtain hot water of a desired temperature at each time of a plurality of times in accordance with the user's lifestyle and life time program. It is intended to provide a hot water storage container.

[0007]

The present invention comprises the following problem solving means in order to solve the above-mentioned problems in the prior art and effectively achieve the object.

That is, an electric hot water storage container comprising a hot water heater and a hot water heater control means for controlling the heat generation state of the hot water heater is provided with a plurality of stages of time setting means and is arbitrarily set by the time setting. User 1
A program timer is provided for programmatically operating the heater control means in accordance with the daily life time program.

The program timer is further provided with a day-of-the-week selecting means so that a different living time program can be set for each day of the week selected by the day-of-the-week selecting means.

[0010]

Therefore, the electric hot water storage container of the present invention operates as follows corresponding to the above configuration.

That is, first, the user uses the time setting means of the program timer, for example, each living time zone of the day, morning, noon, 3:00 PM, evening, night, and a desired time corresponding to the time. Set the hot water temperature. As a result, the boiling water insulation program corresponding to the life time program and lifestyle of the user is automatically set.

After that, the program timer is operated to control the operating state of the water heater controller, and the set day (24 hours) is set according to the passage of time.
In order to obtain the hot water temperature set at each program time in, the heat generation, heat retention, and cooling state of the water heater are sequentially program-controlled.

In this case, when the day of the week selection means is provided in the program timer, the living time zone and the hot water temperature setting program corresponding thereto are set for each day of the week selected by the day of the week selection means. It is set individually, and the heating of the water heater similar to the above is generated accordingly.
Insulation and cooling control are performed.

[0014]

As a result of the above, according to the electric hot water storage container of the present invention, for example, in addition to the normal timer key, a program function selection key or the like is provided to select the program timer function described above, and water supply can be performed. For example, morning, noon, PM3 of the day according to the user's own day or day of the week
It becomes possible to automatically obtain hot water of a desired temperature for each time of day, evening, and night. Therefore, it is very convenient.
