Description

  The present invention heats the content liquid contained in the container with a heater to store hot water, and discharges the stored content liquid from a spout that faces the outside of the front upper end of the container through a pouring path by a pump. It is about the pot.

  Such an electric pot is called an electric hot water storage container, an electric water heater, etc., and various forms are widely used. In particular, there is a problem that the content liquid does not cool because the pouring path for pouring the content liquid to the outside passes through the hot water storage area, and the cooled content liquid is initially poured out by the pouring path located outside the hot water storage area. What is avoided is known (for example, Patent Documents 1 to 3). Since the water will cool down, add the tap water and boil it by boiling it, then store it at the specified temperature and pour it out as needed, or boil it again and pour it out for use. To do.

  In Patent Document 1, an electric centrifugal pump is connected halfway from the bottom of the hot water storage area until it returns to the hot water storage area, and the part that returns to the hot water storage area reaches the lower part of the upper end opening that is opened and closed by the lid of the body. A technique is disclosed in which, after standing up, it goes out of the hot water storage area, enters into a projecting portion to the front of the shoulder portion of the vessel body, and the spout protrudes downward at the front of the projecting portion. The water stop structure that stops water when the body is tilted forward or falls in an abnormal posture is provided in the pouring guide portion in the projecting portion of the pouring path to the front portion of the shoulder portion. The rising guide portion that rises in the hot water storage area of the pouring path is formed in an inverted L shape so that it can be attached to and detached from the lower portion of the hot water storage area of the pouring path and the pouring guide section.

  According to Patent Document 2, a liquid heater is dropped from a lid side into a hot water storage area so that the content liquid can be efficiently heated, and the content liquid is pressurized with an electric pump or a manual pump, The technique which pours out the front part of a container body through the pouring path hanging in the hot water storage area from the lower part of the upper end opening opened and closed by the lid is disclosed.

In Patent Document 3, the content liquid is pressurized with a manual pump, and is poured out of the front part of the container body through a pouring path that hangs into the hot water storage area from the lower part of the upper end opening that is opened and closed by the cover part and the cover of the container body. Disclosed technology.
Japanese Patent Laid-Open No. 11-342076 JP 2000-116516 A JP 2001-87134 A

  By the way, the technique disclosed in Patent Document 1 is located in the middle of being drawn out from the bottom of the hot water storage area of the pouring path by the centrifugal pump and returning to the hot water storage area again, and the content liquid is externally passed through the pouring path through the non-pressurization method. Therefore, the dispensing failure due to pressure leakage does not occur unlike the method in which the content liquid is pressurized and pushed out by an electric pump or a bellows pump. However, although the inverted L-shaped rising guide portion facing the hot water storage area of the pouring channel is detachable and is not easy to clean, it is below the top opening that is opened and closed by the lid of the container, that is, by the lid of the container. As a result of being pulled out to the outside by using the front overhanging part of the container avoiding the opening and closing part, the water stopping structure that stops water in the abnormal posture at the time of forward tilting or falling is applied to the extraction guide part that is not suitable for detachment However, there is a problem that it is difficult to care for even though there are many detail parts.

In the technique disclosed in Patent Document 2, since the pouring path is mounted on the lid together with the submerged heater, it is difficult to care for the entire pouring path, and the pouring path hangs down from above into the hot water storage area. So, in the example of combination installation with the submerged heater, the height to prevent empty cooking between the two can be determined uniquely, but the pouring path is provided on the side of the body separately from the submerged heater on the lid side In the example to do, it is hard to secure the empty cooking prevention function stably because the height of the empty cooking prevention with the submerged heater cannot be determined uniquely between each other. Further, providing the pouring path independently from the lid, that is, avoiding the open / close region by the lid of the container body, has the same problem as that disclosed in Patent Document 1 in terms of care for the pouring path.

  Although the technique disclosed in Patent Document 3 is a non-submerged heater under the bottom, it is not particularly different from that disclosed in Patent Document 2 due to problems of preventing cooking of empty cooking and care for the pouring path.

  The present invention is a non-submersible heater below the bottom of the hot water storage area, and the height to prevent empty cooking is uniquely determined, and follows the pouring path structure rising up the hot water storage area to improve the careability. It is an object to provide a pot.

  In order to achieve the above-described object, the electric pot of the present invention heats the content liquid stored in the container with a heater to store hot water, and the stored content liquid is pumped through the discharge channel to the upper end of the container. In an electric pot used for pouring from the spout facing outside the front part, the pouring path is once pulled out of the bottom of the hot water storage area, then rises again into the hot water storage area, and is a lid that is hinged to the rear of the vessel One feature is that it is provided so as to reach the spout outside the front upper end of the container through the space between the upper end opening and the lid opened and closed.

  In such a configuration, after the pouring path is once drawn out of the bottom of the hot water storage area, it enters the hot water storage area again, rises, and passes through between the upper end opening and the cover that are opened and closed by a lid hinged to the rear of the vessel body. It reaches the spout outside the upper front of the container, and keeps the liquid temperature in the passage at the hot water storage temperature within the range of rising the hot water storage area. It is easy to set up. In addition, if a centrifugal pump is installed in the draw-out section that is drawn out of the bottom of the hot water storage area of the pouring path and returned to the hot water storage area again, the content liquid can be drawn into the pouring path, sent out earlier, and poured out in a non-pressurized manner. If the pressure is increased by a pump, it can be discharged into the discharge path by a pressurizing method. Furthermore, the connection end opening to the bottom of the hot water storage area of the pouring channel can set the height of the hot cooking prevention with the non-submerged heater below the bottom of the hot water storage area from a unique positional relationship with the bottom of the hot water storage area.

  The electric pot of the present invention also heats the content liquid stored in the container with a heater to store hot water, and pours the stored content liquid from a spout facing the outside of the front upper end of the container through a discharge path by a pump. In an electric pot for use, the pouring path is once drawn out of the bottom of the hot water storage area, then enters the hot water storage area again, rises, and is opened and closed with a lid hinged to the rear of the vessel. It is provided so as to reach the spout outside the upper front end of the container body, and a part of it is mounted on the lid side and moved to the separation position and connection position with respect to other parts as the lid opens and closes Another feature is that it has been made to do so.

  In such a configuration, in addition to the case of the one feature described above, even if a part of the pouring path does not pass through the inside of the lid, it is provided on the lid side, so that the other parts can be prevented by opening and closing the lid. It becomes an independent part that is moved to the separation position and the connection position. When the lid is opened, it is removed from the upper end opening of the container, and when the lid is closed, it is returned to the connection state with the other part of the pouring path.

The electric pot of the present invention also heats the content liquid stored in the container with a heater to store hot water, and pours the stored content liquid from a spout facing the outside of the front upper end of the container through a discharge path by a pump.
