DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric discharge storage container, and more particularly, to an electric discharge storage container which discharges a liquid contained in a container out of a container through a lead-out line by an operation of an electric pump. Is about

[0002]

2. Description of the Related Art A large number of electric discharge storage containers of this type have been conventionally provided as, for example, household electric pots.
This apparatus is provided with a water stop valve at the time of overturn which prevents the contents liquid from spontaneously flowing out through the outlet pipe when the body falls down or inclines. Thereby, when the container body falls, the content liquid is prevented from flowing out, thereby avoiding a burn due to the hot water and a wet surrounding area, thereby making it possible to achieve safe use.

In this apparatus, as shown in FIG. 7, a content liquid is guided from an outlet b of a container a to an upper portion and a front portion of the container a.
It has a lead-out conduit c that discharges from the front part of the container body a downward to the outside of the container body a, and is located in the middle of the lead-out conduit c in the vertical direction, specifically, near the discharge port d of the lead-out conduit c. An overturn water stop valve e is provided in the middle part of the upper part. The water stop valve e at the time of falling
A downwardly facing valve port f, and a valve body g which is seated under its own weight at a position directly below and opposed to the valve port f to open the valve port f.
It is composed of

If the vessel a falls down by any chance, the valve body g moves to the valve port f side by its own weight and closes the valve port f, and at the same time, the liquid which is going to flow out naturally fills the valve body g. Since the liquid is pressed against the valve port f, it is possible to prevent the content liquid from flowing out through the outlet pipe c.

[0005]

However, the water stop valve e does not operate when the body a is slightly inclined forward. Therefore, when the container a is tilted forward without going over, the liquid content flows out through the outlet pipe c.

According to an experiment, when the container a is tilted forward by about 30 ° in a full state as shown by H in FIG. 7, the liquid level of the content liquid becomes the angle shown by h in FIG. As a result, the liquid content naturally starts flowing out to the outside through the outlet pipe c, beyond the upper end U-shaped portion i of the outlet pipe c.

[0007] Further, even when the vessel a falls down, the liquid may flow out without closing the water stop valve when the vessel a falls down.

Further, if the outlet pipe is continuous from the inner melter to the discharge port, once the content liquid is discharged,
Even though the discharge operation has been completed, inadvertent discharge such as the fact that the content liquid continues to be discharged due to the siphon phenomenon in the presence of the water stop valve e at the time of tipping is sometimes a problem.

In view of the above, the present applicant has previously proposed an electromagnetic valve in which the outlet pipe is always closed by an electromagnetic valve when the liquid is not discharged, and the electromagnetic valve is opened only when the liquid content is discharged. The problem can be solved.

By the way, recently, by circulating the content liquid while heating it, calcium removal for removing the calcium component in the content liquid is performed, or the content liquid is circulated to repeatedly pass through a water purification material such as activated carbon. The water is being purified.

Therefore, an object of the present invention is to make use of the fact that the electromagnetic valve always closes the outlet pipe during non-discharge, thereby enabling the electric pump to exhibit the function of circulating the liquid content, and switching the electromagnetic valve. An object of the present invention is to provide a convenient electric discharge storage container that can discharge a content liquid without being affected by a circulation function.

[0012]

An electric discharge storage container which discharges a content liquid contained in a container from the discharge port to the outside of the container through a discharge line by an operation of an electric pump, wherein the content liquid is connected to the discharge line. To the circulation position to close the outlet line and lead the liquid to the circulation line side, and to the discharge position to close the circulation line and lead to the outlet line side so that it is always in the circulation position. The solenoid valve, the first control means for operating the electric pump by the setting operation of the circulation mode, and the solenoid valve is switched from the circulation position to the discharge position by the discharge operation and the electric pump is operated to discharge the content liquid from the discharge port. And a second control unit for discharging.

In such a configuration, unless the discharge operation is performed, and after the discharge operation is completed, the solenoid valve provided in the lead-out conduit is always in the circulating position. Even if the outlet pipe is continuous from the inside of the inner container to the discharge port, the outlet pipe remains closed at the position of the solenoid valve, and the content liquid flows out naturally,
Alternatively, it is possible to prevent inadvertent outflow due to the siphon phenomenon. Further, when the circulation operation is performed in this state, the first control means operates to operate the electric pump, and after the content liquid in the storage area is sent out to the outlet pipe, the electromagnetic pump located downstream of the electric pump is operated. Since the liquid is guided to the circulation pipe by the valve and returns to the liquid storage area, the content liquid can be repeatedly circulated, which is effective in repeatedly performing descaling and purification. When the discharge operation is performed, the second control means operates to switch the solenoid valve from the circulation position to the discharge position and to operate the electric pump, so that the liquid content is discharged from the discharge port through the outlet pipe by the operation of the electric pump. The circulation function is not hindered, and the contents liquid can be discharged and used as desired according to the discharge operation, and there is no inconvenience in using the contents liquid.

When the electric pump and the solenoid valve are unitized as in the second aspect of the present invention, they can be arranged by utilizing a dead space in one place such as in the bottom of the body. Since it can be handled as one part, the production and assembly are rationalized and the cost is reduced.

Can be prevented. Further, when the circulation operation is performed in this state, the first control means operates to operate the electric pump, and after the content liquid in the storage area is sent out to the outlet pipe, the electromagnetic pump located downstream of the electric pump is operated. Since the liquid is guided to the circulation line by the valve and returned to the liquid storage area, the content liquid can be repeatedly circulated, which is effective for repeating descaling and purification. When the discharge operation is performed, the second control means operates to switch the solenoid valve from the circulation position to the discharge position and to operate the electric pump, so that the liquid content is discharged from the discharge port through the outlet pipe by the operation of the electric pump. The circulation function is not hindered, and the contents liquid can be discharged and used as desired according to the discharge operation, and there is no inconvenience in using the contents liquid.
