[Technical Field of the Invention] The present invention relates to a hot water storage type electric water heater that can be reserved for one week to heat water using electricity late at night. [Technical background of the invention and its problems] Conventionally, in a type of storage type electric water heater that uses late-night electricity to heat water, whenever the power switch is turned on, if late-night electricity is turned on, the electricity for late-night electricity is used. Since electricity was supplied to the heater, for example, even if you were away from home for several days on a family trip or for other reasons, you would have to supply electricity to the heater late at night every day, especially in winter. When the ambient temperature is low and the heat dissipated from the tank is large, the temperature of the once boiled water drops considerably, which consumes a lot of power.As a result, even though no hot water is used, power is wasted, which is a problem that is uneconomical. It was hot. Also, if you turn off the power switch and are away from home, the heater will not be energized at all late at night, so there will be no problem of wasted power, but you will still be able to use the hot water the same day you return home. First, there was the inconvenience that hot water could only be used the next day after the power switch was turned on. From this, for example, if you set up a memory that allows you to reserve the day to boil water for each day of the week on a weekly basis, and control the power supply to the late-night power heater based on the reservation information in that memory, you can avoid it even if you are away from home. If you set the water to be boiled using electricity late at night the day before you return home, you will be able to use the hot water on the day you return home, which will solve the above-mentioned problem. However, if you set up a memory that can be reserved weekly in this way, for example, if a power outage occurs to the power supply that controls the memory while you are away, the reservation information in the memory will be cleared.
This causes a problem in that the state becomes the same as when the power switch is turned off. In addition, for example, if you use memory to set the hot water temperature control in several stages, if a power outage occurs, the setting information will be disrupted, and for example, the temperature may be low even though it was set to a high temperature. A problem arises in that the water temperature is controlled by temperature. [Purpose of the Invention] This invention has been made in view of the above-mentioned points, and is capable of setting water boiling control using late-night electric power in memory for each day of the week on a weekly basis. To provide a hot water storage type electric water heater which can be forcibly set to operate and can control water heating from the user's side at all times. In addition, this invention allows users to selectively set various temperature settings when boiling water, and when a power outage occurs, the set temperature is forcibly set to the maximum temperature, thereby allowing the user to further control the water boiling. The purpose of the present invention is to provide a hot water storage type electric water heater that can improve performance. [Summary of the Invention] The present invention provides a hot water storage type electric water heater that heats water in the tank by installing a heater for late-night electricity in a heat retention tank and energizing the heater with late-night electricity, each day of the week. A reservation memory is provided corresponding to each day, and information on whether to permit or disallow the supply of late-night power to the heater for late-night power is set, and information on whether to permit or disallow the supply of power by specifying the day of the week to this reservation memory. and means for setting the
When power is turned on late at night, the system determines whether or not the power is allowed to be energized stored in the reservation memory for the corresponding day of the week, and controls whether or not to energize the heater for late-night power.
When at least one of the control power source and late-night power used for these controls goes out of power and is restored, all information in the reserved memory for each day of the week is canceled and instead, power supply permission information is set in all of the reserved memories. This is how it was done. In addition, the present invention further provides a means for selectively setting various boiling temperatures of water in the tank using a memory, and detecting the water temperature in the tank when power is applied to the late-night power heater, and setting the water temperature to the selected setting. means for controlling the power supply to the late-night power heater to be stopped when the specified boiling temperature is reached, and at least one of the control power source for driving these means and the late-night power supply is out of power and the power is restored. The boiling temperature is forcibly set to the maximum temperature. [Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram schematically showing the configuration of an electric water heater in which an insulated hot water tank 11 that can store, for example, 370 mm of water is housed in a case A. This hot water tank 11 has a water supply pipe (see Fig. (not shown) and a hot water pipe (not shown) on the top.
The hot water in the tank is pushed upwards by water supplied from the water supply pipe. Said hot water tank 1
Temperature sensors 12, 13, and 14 are attached to the external side wall of 1 to detect the amount of remaining hot water and the temperature of the hot water. That is, the first temperature sensor 12 is installed at a position that detects the hot water temperature and the remaining amount of hot water "230", the second temperature sensor 13 is installed at a position that detects the remaining amount of hot water "120", and the third The temperature sensor 14 is installed at a position that detects the amount of remaining hot water "60". In addition, the hot water tank 11
A late-night power heater 15 and an auxiliary heater 16 are attached to the lower inner wall of the late-night power heater 1.
A fourth temperature sensor 17 is installed below 5 to detect the temperature of the water supply. The case A is provided with an operation section B, and the operation section B has day reservation switches 18a and 18 corresponding to each day of the week from "Sunday" to "Saturday" as shown in FIG.
b, 18c, 18d, 18e, 18f, 18g and day of the week LED (light emitting diode) 19a, 19b,
19c, 19d, 19e, 19f, 19g are arranged, as well as an LED for displaying today's day of the week.
20a, an LED 20b for displaying a reservation for a boiling day, and a selection switch 21 for switching between setting today's day of the week and setting a reservation for a boiling day. In addition, the operation part B has an LED for displaying the fixed hot water temperature setting.
22a, LE 22b for displaying automatic hot water temperature higher setting, LED 22c for displaying automatic hot water temperature standard setting, and LED 22d for displaying automatic hot water temperature lower setting are arranged, and hot water temperature control can be set to "fixed", "high automatic", or "standard automatic". A hot water temperature changeover switch 23 is provided for selectively setting one of the "lower automatic" modes. Here, "fixed" water temperature control refers to water temperature control that raises the water temperature to a maximum temperature of 87℃, regardless of the state of the water supply water temperature, and "high automatic" and "standard automatic"
"Low automatic" hot water temperature control refers to performing hot water temperature control as shown in the table below depending on the state of the water supply water temperature.
