Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric water heater for heating and keeping a contained liquid warm.

BACKGROUND OF THE INVENTION Conventional electric water heaters with electric hot water supply function, for example, as shown in Japanese Utility Model Application Publication No. 60-173247, use an electromagnetic pump with AC power supplied to it to supply pressurized air. A method is used to draw the liquid out of the container by generating pressurized air and sending the pressurized air into the container to increase the pressure inside the container.The operating method is as follows.
This method opens and closes a switch that controls the ON-FF flow of electricity to the electromagnetic pump by suppressing the knob provided on the lid. It was watermelon.

Problems to be Solved by the Invention However, with such a conventional configuration, only a certain amount of liquid always comes out when drawing out the liquid in the container. If the flow rate per unit time is set to be high when pouring into a large-capacity container such as a pot, the force will be too strong and the hot water will splash out, potentially causing burns, which is extremely dangerous. On the other hand, if you set the flow rate low to match a small-capacity container, it may take too long to fill the pot, etc.
It was not easy to use.

In addition, since it is an air pressurization type, it is necessary to close all three steam passages when discharging the liquid. Therefore, when the knob is pressed, a mechanism is required to close the steam passages at the same time, and as a result, the operating load is reduced. There were problems such as increased size and increased cost.

The object of the present invention is to provide an electric water heater that solves these problems.

Means for Solving the Problems In order to solve the above problems, the present invention provides a container for storing a liquid, a heating element for heating the liquid in the container, and a system for discharging the liquid in the container to the outside of the container. electric liquid pump,
A knob is provided to adjust the opening area of the discharge port, and a changeover switch is provided that operates in conjunction with the knob to turn on and off power to the motor of the liquid pump. The discharge flow rate is controlled.

Effect According to the above configuration, when pouring into a relatively small capacity container such as a coffee cup, the rotational position of the knob is adjusted to reduce the flow rate per unit time, and when pouring into a relatively small capacity container such as a pot. The operator can freely choose the flow rate, such as increasing the flow rate when pouring hot water into the water.This eliminates the danger of hot water splashing and causing burns, and greatly improves both safety and operability. It is something.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. In the figure, 1 is a body that covers a container 2, a spout 3 is fixed to the upper opening of the body 1, and a hook 4 is integrally attached to the lower end of the body 1. 06 is a spout. The spout 3 is opened by pressing the lock knob 6 provided on the front surface of the lid 5.
It is configured so that it can be attached to and detached from it.

7 is a steam port, and this steam lower communicates with the inside of the container 2.

8 is a guide hole provided at the lower side of the container 2;
is connected to the suction port 1 of the electric liquid pump 1o via an abbreviated waterproof backing 9 made of silicone rubber or the like.
It is connected to 1. 6. In this liquid pump 10, a motor 12 rotates a vane in the pump 10 to send out the liquid in the container 2, and the liquid is delivered to the spout 1 of the liquid pump 1o.
3, passes through a discharge pipe 14, passes through a water pipe bushing 16 containing an outflow prevention valve 16, and is discharged from the discharge port 17 through a discharge pipe 19 in the nose 18 to the outside of the vessel.

On the back side of the bottom of the container 2, a heating element is made of a metal with good thermal conductivity such as aluminum or steel, with insulating plates stacked on top and bottom and a main heating element 2o and an auxiliary heating element 21 integrally formed. It is fixed to the heat diffusion plate 22 and the back plate 23 in a crimped state.

24 is a first temperature regulator that performs ON-OFF control of the main heating element 2o, 26 is a second temperature regulator that performs ON-OFF control of the auxiliary heating element 21, and 26 is used to switch between the motor circuit and the heater circuit. It is a changeover switch.

Reference numeral 27 denotes a flow rate control valve provided in a valve portion 28 provided in a part of the discharge port 17, and this flow rate control valve 27 has a flow path 29 in the center.
The flow path within the partial outlet 17 to the discharge 6 can be adjusted from open to closed by a rotation of 9o0.

30 is a cam provided in a part of the flow rate control valve 27, and this cam 3o is adapted to be interlocked with the changeover switch 26.

31 is an operating knob.

Next, the operation will be explained based on the electric circuit diagram shown in FIG. 2 and FIGS. 3 and 4.

When the user tries to tap the hot water and turns the operating knob 31, the changeover switch 26 linked to the cam 3o is activated.
Voltage is applied from the heater circuit to the motor circuit, and the pump 1o starts operating. At this time, the voltage applied to the motor 12 is constant, and therefore the amount of liquid sent to the outside is regulated by the flow path 29 of the flow rate control valve 27.

When the hot water has finished dispensing, the flow path 29 becomes perpendicular to the flow path in the discharge port 17 to close the opening of the discharge port 17, and the changeover switch 26 linked to the cam 30 switches the heater from the motor circuit. Switch to the circuit and pump 12
If the operating knob 31 is always biased to the position where the operation of the bon 7 and vane 12 is stopped using a kick spring or the like, the operating knob 31 can be removed from the operating knob 31 after the operation is completed. When released, hot water will automatically stop flowing.

Effects of the Invention As is clear from the description of the above embodiments, the electric water heater of the present invention allows the amount of hot water to be adjusted at any stage.
For example, when pouring into a small-capacity container, by reducing the flow rate per unit time, you can prevent hot water from splattering, etc., and also prevent the container from overflowing and spilling. When pouring into a container with a large capacity, the time required for pouring hot water can be shortened by increasing the flow rate per unit time.

In addition, its configuration can be achieved with a simple electrical circuit that only requires a DC conversion circuit and a changeover switch, and the flow rate adjustment configuration can be achieved with a simple configuration, so it can be obtained at relatively low cost. be.
