Abstract

PURPOSE:To boil up water according to seasons and each hot water supplying level by a method in which plural boiling temperatures optimum to the seasons are memorized and the supplying levels of hot water are set up. CONSTITUTION:Boiling temperatures according to seasonal periods are memorized in a memory in a control unit 1. The temperatures of hot water detected by a detector 3 to detect the temperature of hot water in a hot water storage tank 2 are compared, and a midnight powered heater 4 is controlled by a power supply conttroller in the control unit 1 to control the power supply of the heater 4 as a heating source. The control unit 1 consists of a memory 5 to store plural boiling temperatures according to the heating period and the hot water supplying level, a setter 6 to set up the hot water supplying levels, a judging means 7 to judge seasonal periods, a selector 8 to select boiling temperatures in the memory on signals from thesetter 6 and the judging means 7, and a power supply controller 9 to control the heater 4. Desired boiling temperatures can thus be obtained according to each hot water supplying level, and wasteful radiation of heat can be lessened. The amount of residual hot water can also be reduced.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a hot water storage type water heater.

Configuration of conventional example and its problems Conventional water heaters of this type control heating by a climate control means that controls the temperature by the output from the water temperature sensor in the hot water storage tank, and -1- The hot water in the tank was heated by temperature change.

At this time, the boiling temperature (if) is mostly fixed at a certain temperature, and when the demand for hot water decreases, such as during the summer, the remaining hot water in the hot water storage tank may be as high as 111°, and as a result, the water is released. This has the disadvantage that the amount of heat increases and the efficiency of the equipment decreases significantly.

1-1 The present invention is intended to solve such conventional problems, and aims to perform boiling in accordance with the season and each hot water supply level.

Structure of the Invention In order to achieve this object, the present invention includes a heating source provided in a hot water storage tank section, a determining means for determining a period such as a season, a setting section for setting a hot water supply level, and a heating source provided in a hot water storage tank section. Selection 1S1 (with a part of memory having a plurality of memories storing boiling temperatures according to levels, and a selection 1S1 for selecting a boiling temperature in the part of memory based on signals from the period detecting means and the setting part); A hot water temperature detecting means for detecting the temperature of hot water in a hot water storage tank, and a heating controller for controlling the heating source based on signals from the selection section 110 and the hot water temperature detecting means are provided.

This configuration allows you to store multiple boiling water temperatures depending on the season, and boil water according to each water supply level.

Example theory 131. ] Hereinafter, embodiments of the present invention will be explained using FIGS. 1 to 3.
do. Electric water heaters that use electricity late at night can heat up the hot water needed for the next day within 11 hours of electricity from 11pm to 7am the next morning. Figure 3 shows how to determine the monthly required amount of hot water based on monthly water temperature changes and hot water supply rates, and then calculate the boiling temperature according to the seasonal period by adding the hot water supply level factor to the required hot water temperature. This is the graph shown. In FIG. 1, the boiling temperature is stored in a part of the memory in the multiple control unit 1, and compared with the hot water temperature detected by the hot water temperature detecting means 3 that detects the hot water temperature in the hot water storage tank 2. The late-night power heater 4 is controlled by an energization controller (heating controller) in the control unit 1 that controls the power supply to the late-night power heater 4, which is the power source. It's 1.
As shown in FIG. 2, the control unit 1 includes a memory part 5 that stores a plurality of boiling water temperatures according to periods and hot water supply levels.
, a setting unit 6 for setting the hot water supply level, a determining unit 7 for determining a period such as a season, and the setting unit 6 and the setting unit 6. It is composed of a selection section 8 that selects the temperature, and an energization controller 9 that controls the late-night power heater 44. According to this configuration, the water is heated to a desired temperature according to each hot water supply level. The remaining hot water is 111. This has the effect of reducing wasteful heat radiation.

Next, another embodiment of the Kibatsu 1 will be explained using FIG. 4. The difference from the above embodiment is that the memory part 5 is a first memory 10 that stores the reference sieving water temperature, and a correction value for the reference sieving water temperature stored in the first memory 10. According to this structure, the reference sieving water temperature corresponding to the season is stored, and the difference from the reference sieving water temperature is stored. This has the effect of reducing memory capacity.

In addition to late-night electric water heaters, Kibari J can also be used for hot water storage type water heaters that use gas or oil as a heat source. - Effects of the Invention As described in section 2, the water heater of the present invention provides the following effects.

(1) Since it is configured to store multiple types of boiling water temperatures according to the season, it is possible to boil water according to each water supply level, reducing the amount of remaining hot water and reducing wasted heat radiation. , highly energy-saving.

(2) Simply enter the hot water level and the water will be heated according to the season.”
It is very convenient because it boils the boiled rice without wasting energy.
