Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a water heater having a function of displaying whether water is being supplied.

Conventional configuration and its problems In recent years, with the spread of coffee, ramen, etc., opportunities to use large amounts of hot water have increased. Therefore, there is a demand for a water heater that can provide a large amount of hot water at any time and safely.

When using a water heater, especially if the hot water supply status is not visible to the user due to the container, etc., the user may manipulate the container that is supplying hot water even though hot water is being supplied, spilling hot water and staining the surrounding area. Or there was a risk of getting burned.

As a solution to this problem, a water heater as shown in the block diagram of FIG. 1 was proposed. That is, a hot water storage tank 1 for storing hot water, a hot water supply means 2 for discharging hot water from this hot water storage tank 1, a basket 3 for temporarily storing and discharging hot water discharged from this hot water supply means 2, and a switch 4 operated by a user. , by operating this switch 4, the hot water supply means 2 is turned on for a certain period of time.
It is composed of a first timer 5 that operates the first timer 5, and a display means 6 that indicates that hot water is being supplied by the output of the first timer 5. When the switch 4 is operated and the first timer 5 is operated, the hot water starts being supplied. When the means 2 was activated to supply hot water, the display means 6 was also activated to display to the user that hot water was being supplied.

However, although this conventional water heater can display that hot water is being supplied during hot water supply, after the hot water supply means 2 has finished operating,
Due to the residual hot water remaining in the basket 3, hot water supply was not completed until after the time determined by the amount of hot water remaining in the basket 3 after the operation of the hot water supply means 2 was completed. As a result, even after the hot water supply display has ended, hot water continues to be supplied using the remaining hot water in the basket 3, creating a dangerous situation in which there is no indication that hot water is being supplied even during hot water supply.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks and provides a safe water heater having a function of appropriately displaying the hot water supply status.

Composition of the Invention The hot water supply device of the present invention includes a hot water storage tank for storing hot water, a hot water supply means for discharging hot water from the hot water storage tank, a basket for temporarily storing and discharging the hot water discharged from the hot water supply means, and a water heater operated by a user. a first timer that operates the hot water supply means for a certain period of time by operating the switch; and a second timer that operates for a time proportional to the timer time after the timer has finished operating. and a display means for displaying that hot water is being supplied by the output of the first timer or the second timer. Therefore, after the hot water supply means stops, the time for the remaining hot water to be discharged from the basket increases or decreases in proportion to the time the hot water supply means is in operation.
The display means is activated for a period of time proportional to the activation time to notify the user that hot water is being supplied, thereby preventing accidents.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In FIGS. 2 and 3, 1 is a hot water storage tank to which a heating heater 11 is attached.
It boils water and keeps it warm. Reference numeral 12 denotes a pump that supplies hot water from the hot water storage tank 1 to the basket 3. Hot water is temporarily stored in the basket 3, and coffee beans and tea leaves are soaked in the hot water to perform extraction inside the basket 3. When the user operates switch 4, the oscillation IC
By adding a capacitor 19 and a resistor, the oscillator 13 oscillates and outputs an oscillating wave with a frequency determined by the oscillation adjustment variable resistor 14 operated by the user. and a first one connected to the oscillator 13.
The counter 15 operates a relay 16 until a predetermined number of counts are counted from the start of oscillation of the oscillator 13, and this relay 16 operates the hot water pump 12. The second counter 17 starts counting the oscillation waves of the oscillator 13 after the first counter 15 finishes counting, and operates until it counts a constant times the predetermined count number of the first counter 15. 18
is a lamp that indicates that hot water is being supplied by the first counter 15 or the second counter 17.

The operation of the above configuration will be explained. When the user operates the switch 4, the oscillator 13 outputs an oscillation wave determined by the oscillation adjustment variable resistor 14, and the first counter 15 starts counting. The first counter 15 outputs an output until it reaches a predetermined count, activates the relay 16, and drives the pump 12 to supply hot water. Furthermore, the lamp 18 is also activated to indicate that hot water is being supplied. After the first counter 15 finishes counting, the second counter 17 starts counting and outputs an output, and lights up the lamp 18 to indicate that hot water is being supplied.
And the second counter 17 is the first counter 15
The hot water supply display is performed until the remaining hot water discharge end time, which is determined by the operating time of the hot water pump 12, by completing the operation after counting a constant times the count number of the hot water supply pump 12.

Effects of the Invention As is clear from the above explanation, the hot water supply device of the present invention not only displays the indication that hot water is being supplied, but also discharges all the hot water remaining in the basket for brewing coffee or tea from the hot water supply device. Since the display is displayed until the hot water is finished, the user can be warned not to get burned by touching the hot water container while the hot water is being discharged, and it can be used cleanly without spilling hot water, so it has great industrial value. There is something.
