Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric water heater capable of heating and retaining a contained liquid and pouring the liquid into an external container.

[0002]

2. Description of the Related Art When an electric water heater is used, the inner surface of the container is often soiled due to water stains, scale adhesion, etc. by boiling water.
There is a configuration in which the container portion is detachable so that the inner surface of the container can be easily cleaned, and the container can be washed directly by a sink or the like.

FIG. 4 is a vertical cross-sectional view showing the structure of a conventional electric water heater. As shown in FIG.
Can be set in the main body 102, and the outlet path of the liquid in the container can be set from the outlet port 103 at the bottom of the container to the bushing 104.
To the pipe 105, and then to the pipe 105 via the water conduit 107 in the lid 106, and again from the discharge port 108 in the main body to the outside of the body. When tapping hot water, the push plate 109 of the lid was operated to send air into the bellows (not shown) to raise the internal pressure and push the hot water out.

[0004]

However, the above-mentioned structure has the following problems when the lid is opened.

(1) When the lid is opened, the connecting portion of the lead-out path with the lid body is opened upward, and is contaminated with dust in the air, which not only spoils the appearance but also It was hygiene.

(2) If the method of drawing hot water is not based on the bellows of the lid (for example, the pumping method using an electric pump), the electric pump operates by mistake even if the lid is removed, and hot water is unexpectedly opened. There was a risk of burns, getting the floor wet, and pouring hot water into the charging part of the body, etc., from the connected part in the state.

In view of the above points, an object of the present invention is to provide an electric water heater that is not unsanitary, is safe, has excellent operability, and has few failures.

[0008]

SUMMARY OF THE INVENTION The present invention has a lid that covers the upper surface of a container that is detachable from a body that contains a liquid, and the liquid in the container is led out of the container from the container. It is configured so as to go through a lead-out path that goes outside the body without passing through.

Further, there is a lid for covering the upper surface of the container detachable from the body for containing the liquid, and the lid is provided in front of the inlet on the lid side of the lead-out path from the container through the body to the outside of the body. It is equipped with a valve that interlocks with the opening and closing of.

[0010]

According to the present invention, since the outlet path of the container detachable from the main body for containing the liquid is provided from the container to the outside of the body without passing through the inside of the lid, the lid can be opened. Even if left unattended, it is possible to prevent dust or the like in the air from entering the lead-out path and becoming dirty or unsanitary.

Further, a valve interlocking with the opening and closing of the lid body in front of the inlet on the lid side of the lead-out path from the body containing the liquid to the container which is detachable from the body, passes through the body, passes through the lid covering the upper surface of the container and reaches the outside of the body. Since the lid is open, the outlet path is closed when the lid is open, preventing the hot water in the container from accidentally coming out and also preventing dust from entering the path when opening. It is also hygienic.

[0012]

1 to 3 show respective embodiments of the present invention,
1 and 2 are vertical cross-sectional views, and FIG. 3 is an enlarged cross-sectional view of a main part of FIG.

In FIG. 1, reference numeral 1 denotes a substantially cylindrical container having a closed bottom and an upward opening, and a flange 2 at the upper end of the container 1 has a handle (not shown) which is attached and detached via a container packing 3.
It is supported by the spout 4 equipped with.

A waterproof metal fitting 5 is provided below the container 1 and is connected to a water pipe 7 through a bushing 6 to form a part of a lead-out path 8.

In FIG. 1, a discharge port 10 having a fall-out prevention valve 9 built therein is provided at the tip of the water pipe 7 and reaches the discharge pipe 11 at the tip.

The fall-off prevention valve 9 is normally lowered downward, but when the body falls down, the fall-out prevention valve 9 moves to the narrow portion 10a in the discharge port 10 to block the passage there to block hot water. Prevent outflow.

This part forms one unit (container unit), and when the container is attached and detached by holding the above-mentioned handle, it is put in and removed from the main body together.

As described above, in the present embodiment, the lead-out of the inside of the container to the outside of the body is performed via the lead-out path 8 that does not pass through the inside of the lid 31 from the container 1 to the outside of the body.

In another embodiment shown in FIGS. 2 and 3, the tip of the water pipe 7 is a case 13 provided with a valve 12,
When the lid is closed, it is connected to a discharge port 10 having a fall-out prevention valve 9 inside the lid.

Numeral 15 is a packing provided at the inlet of the discharge port 10 of the lid, and the case 13 and the discharge port 10 are in close contact with each other. The valve 12 is biased upward (arrow a) by a spring 16 and closes the outlet of the case 13 when the lid is opened and when the container is removed, but when the lid is closed, a rod provided below the discharge port of the lid is closed. 17 pushes the valve 12 downward (arrow b) against the spring 6 to open the outlet of the case and establish communication with the discharge port 10. As described above, the present embodiment has the valve 12 that is opened and closed quickly before the lid 31 side entrance of the lead-out path 8 that extends from the container 1 through the inside of the body to the outside of the body through the inside of the lid 31.

In FIGS. 1 and 2, there is a heating element portion 23 at the bottom of the inner frame 22 of the main body 21, and a sensor at the center.
When the container 1 is set, the sensor 24 comes into close contact with the bottom surface of the container, detects the liquid temperature in the container, and the control circuit 25 detects the temperature of the heating element 23. Take control. The sensor 24 also detects whether or not the container 1 is set. That is, when the container 1 is not set, the sensor 24 does not have a load from above, so it pops out upward, and at this time, the limit switch (not shown) operates so that the sensor 24 cannot be energized.

Reference numeral 26 is a body that wraps the inner frame through a space, and 27 is an upper frame that is placed on the body 26, and holds the body together with a lower hook 28.

The lid 31 placed on the above-mentioned spout 4 is
It is supported by the hinge part. Inside the lid, there is a bellows (not shown) that sends air into the container, and the hot water in the container is discharged outside the container as the push plate is operated.

Although the type having the bellows inside the lid has been described here, the same applies to the case of tap water discharge by an electric pump or the like.

[0025]

As described above, in the electric water heater of the present invention, the lead-out path of the container detachable from the main body for containing the liquid is provided from the container to the outside of the container without passing through the lid. Therefore, even if the lid is left open, it is possible to prevent dust and the like in the air from invading the lead-out path to become dirty or unsanitary.

Further, the container has a lid for covering the upper surface of the container detachable from the main body for containing the liquid, and the lid is provided in front of the inlet on the lid side of the lead-out path from the container through the main body to the outside of the container. Since the valve that interlocks with the opening and closing is provided, when the lid is open, the outlet path is closed, preventing the hot water in the container from accidentally coming out and preventing dust from entering the path when opening. It is also safe and hygienic.

As described above, according to the present invention, an electric water heater having excellent operability and safety in use can be provided at low cost.
